Skip to comments.Firefox won't cache images
Posted on 10/23/2010 5:51:21 PM PDT by library user
I'm usually pretty good at answering my own PC/web questions, but no matter what size I set the FF cache too, every time I go to the same web site, the same images are re-loaded over and over again, each and every visit.
Is there a way to get around this?
Maybe type about:config in the address bar and tinker with a setting in there?
Any suggestions most appreciated.
what version ?
Check the web page source, perhaps they are specifying no cache.
3.6.10 - I know there’s a 3.6.11 but haven’t updated just yet.
They can do that?! What a rip!!!
It may or may not be a browser problem. Go to about:config and type ‘cache’ in the search window and make sure all caching options are enabled. Some web pages have caching disabled through an instruction in the Http header. Check the html source to see if you see a “pragma= no cache” or something like that.
Fire the fox and hire a competent secretary.
Is this a porn site you’re talking about?
Tkink I found it.
Change it to true? It’s currently false.
I am an “Internet Professional” by trade so can I be the first in this thread to ask “Are you logged in?”
Sometimes it's for security reasons.. eg in public computers where the last user's login id/pwd or CC # could remain in the cache. Or it could be because of frequently changing content that don't always update in the browser because the browser reads a cached version.. Any number of reasons.
Magic 8 ball says:
Let that remain false ! SSL information is generally sensitive information like your credit card # and it's a good idea NOT to cache them, especially if your computer is used by others.
Oh, shoot, I already changed it to true. I’ll go back and put it to false. However, the images on the web site did remain cached after I changed the setting to true.
I am only allowed 5GB per month with my current internet plan. Are there some settings you can recommend I change in Firefox to decrease the bytes I’m downloading while surfing the web?
I tried turning off images all together but that’s no fun.
Recipes shouldn’t take up that much space. Feel free to put them back on, if you need too.
Does the url of that site, or at least of the images there begin with ‘https:’ That would explain it. To check the url of the images, right click on an image and then properties . The ‘s’ stands for ssl (secure socket layer)
Nope, it’s just http — and I searched the source code for the word “cache” and it does not appear. Strange.
Interesting. Now I am curious. Sometimes a website will deliberately introduce a random number in the address to prevent the browser from caching. Something like
(&.rand =IHKJHKJ*&...) Since the random number is different every time you refresh the page, the browser is fooled into thinking it’s checking a different address every time, so it reloads everything. But I doubt that’s the case here. You said the browser started caching only after you enabled ssl caching even though the site itself non ssl. Strange.
Are any of them for a killer meatloaf?
“I am only allowed 5GB per month with my current internet plan. Are there some settings you can recommend I change in Firefox to decrease the bytes Im downloading while surfing the web?”
I’ll write this out as best I can...
1. go to http://www.abelhadigital.com/hostsman and download hostsman.
2. install hostsman
3. run hostsman
4. In the menu bar go to Hosts->manage Hosts
add the following sources for host file automated updates:
In alphabetical order:
* Site: http://www.hosts-file.net/
* Source: http://support.it-mate.co.uk/downloads/hphosts.zip
* Mirror: http://hphosts.gt500.org/hosts.zip
hpHosts (Ad and tracking servers only)
5. in Hostsman menu bar go to Hosts-> Optimize Hosts
Open Firefox browser...
6. go to http://netticat.ath.cx/BetterCache/BetterCache.htm and install BetterCache
7. go to https://addons.mozilla.org/en-US/firefox/addon/2489/ and install CacheViewer. (This is NOT required, however it simplifies working with your firefox cache.)
8. go to http://flashblock.mozdev.org/ and install flashblock
9. go to http://noscript.net/ and install noscript extension
10. go to http://code.google.com/p/uctb/ and download Undo Closed Tabs Button extension
11. go to https://addons.mozilla.org/en-US/firefox/addon/9609/ and install ghostery extension
Note that hostsman will control the HOSTS file and remove 95% of all advertisements on the internet. Drastically reduces your bandwidth use on textbased browsing. However it will also block some websites you might use regularly... such as facebook.com, you need to use the Hostsman HOSTS editor to remove any url from the blocklist ....
Note that BetterCache is extremely aggressive in default settings... you will have to decide on the caching options... it takes some time to find what works for you.
Excellent, thank you very much for that!
Hope you are using windows.
Depending on which windows version you use you might have to give hostsman rights to run as administrator... right click the desktop icon, go to properties-> compatibility-> run as administrator tick box, apply.
you can also add it to your Startup folder so it starts when windows starts. So the UAC doesn’t pop up every time you open hostsman.
Absolutely necessary in Vista, a best option in Win7, and not needed in WinXP.
NOW LOWER MY TAXES
I’m trying to understand Mi-Me. Can you explain? I’m trying to add a site to Better Cache which will allow it to always cache, but instead of just being able to enter the URL, it asks for Mi-Me. I checked Wikipedia for more on Mi-Me, but I still don’t understand.
I set it up so long ago I had to relearn it... but I found the website I first used to speed up bettercache! I suggest reading the whole thing... it has more than what I posted above:
BetterCache - Firefox extension
descrip: forces caching of web pages regardless of no-cache headers which webmasters sometimes put in place to prevent caching, sometimes for a good reason and sometimes just to annoying the living doo-doo out of you i think.
suggested config: In the “always cache list” delete the wildcard (the *) in the MIME type area and insert the following (the important ones are bolded while the rest are optional):
Delete everything in the “never cache list”.
usage: nothing to do other than enable/disable it from its options. Go here for more confusing info on MIME types.
caveats: if content of a MIME type you specify is cached, but then is changed on the server, the page may not display correctly (think CSS for instance). Could potentially break sites that depend on such content, though i haven’t had any problems... yet. You should be able to just refresh the page if something if something looks fishy, but if that doesn’t work then you’ll have to either flush your cache, temporarily disable BetterCache, or buy a new computer.
If you’re crazy enough, you can install an industrial level proxy cache like squid (http://www.squid-cache.org/) and it will help keep low that download rate even for a whole network. If you aren’t that crazy, what JerseyHighlander #15 said should be enough.
Right, I forgot why I remembered you needed CacheViewer.
With BetterCache you can easily change the browser.cache.check_document_frequency setting which normally has to be done in about:config. This alone makes it worth having. I used it together with the CacheViewer add-on which shows mime-types that you can then use in BetterCache. This add-on is tremendously useful on sites like Google Books if you have dial-up. It only saves two or three pages at a time so if you’re reading along and want to go back a few pages you have to wait for the whole damn thing to load again. Just set BetterCache to save the mime-types you want and set “Check pages for actuality” to Never and you’re golden. :-)
OK, thanks guys. Seems like a lot of work, though. I was hoping to just install one or two things and be done. This seems more manual and laborious than I was expecting. :O)
Have you tried the latest version of Opera? It has settings for slow connections that reduce download sizes of pages and images. Also, it is the easiest browser to use with images disabled, easy toggle right there on the page.
You can also run Opera Mini on your desk top. This is the smart phone version of Opera. The pages look good, and there is only a fraction of MBs used compared to the regular browsers. If interested, a quick search will fix you up.
I had heard that about Opera. I’ll give it a try. Thanks!
How did this turn out?
If you do use Opera Mini you can install Hostsman in my above post and you’re good to go.
