I have had on and off problems with Firefox working, but up until now, restarting the computer solved the problem. Now it won't load any website for anything...it keeps circulating with "Connecting...". Internet Explorer works just fine and the internet is working with all other devices, the only thing I can find that may be impacting is that the internet has no IPv6 access (I have no clue though and the box is checked). I have tried all of the advice I have found on other similar posts such as disabling the IPv6 and the Prefetch through 'about:config', I restarted the computer multiple times, unplugged the router, checked the firewall and removed and re-added Firefox, cleared the cookies and cache, reinstalled Firefox, uninstalled Chrome.

Nothing seems to be getting me any closer to having Firefox up and connecting again.

As a side note, I only have been having those on and off problems, and this current problem, while connected to my home internet--other connections have had no problems. Also, I am using Norton Antivirus which is up to date and showing no problems at present.

Any ideas on how to fix?

When I ran a security scan using Windows Defender, it says that three files in my Cache2 entries folder are suspicious and should be sent to Microsoft for further analysis. I am wondering if I should be concerned about this. Could these files be malware, spyware, or viruses? I will clear cache, but just want to make sure if the security of my system has been compromised. Thanks!

Just trying to figure out why when I clear the Firefox app cache through the app prefrences it doesn't seem to clear the cache shown in the sc. I once found the app cache in the file system but I forgot where to go to find it and I would like to have the space back. I would also like to know if Firefox files identify themselves under any other name than having "firefox.app". (as an example like maybe .frf?)

I can't clear my browser (Firefox) cache without signing out of all of my active logins, which is really inconvenient. I make sure I have the box for that unchecked, and only have the first four boxes checked, but whenever I clear my cache Firefox signs me out of every website I'm signed in on. It takes a lot of time to log back in to all of them.

This problem just started since yesterday, when I installed the latest Firefox update.

My OS is Windows 7 Ultimate 64-bit.

Since updating Firefod to V58.0.2 my Cache History is no longer being cleared. My settings are shown in the atteched image.

One of my startup tabs is BBC weather for my location. With "Clear Cache History" ticked I should be seeing today's weather, but since updating to 58.0.2 I now see yesterdays weather and I have to refresh the page each time.

Anyone else finding this problem ?

This has been an on going issue with ebay and being able to cash the newest listing under "Time Newly Listed". I now know this is a firefox issue. What happens is I refresh the page under the search "Time Newly Listed" and it is not pulling the newest listings. and the search returns are vary from 84,000 on one refresh and 30 seconds later it might be 83,400. Okay 10 seconds later it may show a return of 83,650. I understand that items will drop off and new ones listed but in the category I am in, a 100 listings just do not drop off in 10 seconds time. This has been an issue for just over nine months and I was taking this as an Internet Service Provider issue. It's not and it has to be an issue with firefox as this is just to erratic and this really was not an issue nine or so months back. Any help would be appreciated, Kip

Hello! I have encountered the following problem: when I open a page with a lot of large images, Firefox obtains a lot of memory and doesn't release it after heavy tab is closed. When I open about:memory tab, it shows several images from closed tab under Explicit/images/content/raster/used. For example, now it uses 1206 MB and I don't know how to release this memory without restarting. Garbage collection and cycle collection on about:memory page don't help.

I wish to configure my Firefox so that it will cache everything and keep this cache, so that when I restart Firefox and am offline, it loads everything from cache and displays fully loaded websites, even though I am offline.

Only when I try to access a not yet opened website or force reload of a website, it shall try to get things from the Internet and fail, since I am offline.

What settings are needed for this to work?

I usually start Firefox continuing my last session, so it feels like a huge waste to reload everything, mostly websites that do not change much anyway. It would be nice to have them display instantly, because everything is already on my local machine and on top be able to read all the websites I already loaded offline, since everything is cached.

I would like to be able to completely refresh all scripts, images and code (absolutely everything on the page) when I click refresh for a tab. I am a web designer and firefox often serves up old content, regardless of whether I manually empty the cache or click refresh multiple times on a page. I tried some chanegs in the config file too which I saw for earlier versions of firefox but they don't seem to have helped. Any suggestions similar to cmd-shift-r that force a complete refresh of a page would be very much appreciated. Even if there is a way to turn caching off completely so that surfing the web was slower that would be preferable to be able to test site updates correctly. I use firebug so if there is an option in there for forcing full refresh of pages that could also help. I am using the most current version of firefox (43.0.4). Thanks

A lot of websites use media extensions to stream videos these days. However I can't find these files in the cache. How come when I completely downloaded a video so I can replay it without downloading (I can even turn off network) I can't get it out of Firefox? All the extensions seem to need some additional download or program too. How come if it's already downloaded? I'm on Fedora GNU+Linux. Thanks!

Prevent Firefox from Clearing the Cache Automatically

Hi all, I'm a photographer and I've been using Firefox as my default/go-to browser for dealing with images-related things like uploading and downloading to server, access… (read more)

Hi all,

I'm a photographer and I've been using Firefox as my default/go-to browser for dealing with images-related things like uploading and downloading to server, accessing and opening photography-related sites and accounts such as Flickr Pro. I'd like to know if any of you can help me with my problem with cache.

So I've noticed that when using Firefox, oftentimes the cache is being cleared/purged automatically, for reasons I don't know yet. I'd like to know how I can keep the cache, or in other words, prevent Firefox from clearing the cache for any reason whatsoever. I really need the cache and I don't mind keeping a large or even massive cache. I'm browsing the same sites over and over again and I'd like to keep the cache instead of having to download it again everytime I browse the sites with Firefox.

The problem is I've tried things like disabling smart cache size and increasing my disk cache to 4 GB to no avail. Firefox always clears the cache automatically after certain period of time or under certain or specific condition(s). The thing is I don't know how to stop Firefox from tampering with my cache. None of my add-ons is actually tampering with the cache, nevermind clearing it.


Several settings that I've changed/modified manually:

・ browser.cache.auto_delete_cache_version: set to -1.

・ browser.cache.check_doc_frequency: set to 2.

・ browser.cache.disk.capacity: set to 4096000. I read somewhere that a Firefox users and a fellow photographer managed to increase the size to 16 GB with his Firefox 69 and is able to keep his cache until he clears it manually, but I failed to repro his steps since my Firefox always reverted back to 380 MB or something whenever I did that. He's probably using custom userChrome and/or userContent css.

All these settings are set to false: ・ browser.cache.disk.smart_size.enabled ・ browser.cache.disk.smart_size.first_run ・ browser.cache.disk.smart_size.use_old_max

・ browser.cache.memory.capacity: set to 2048000.

・ media.cache_size: sometimes I set this to 4096000 to see if it helps with anything, but most of the time it is set to its default value (unchanged).

・ browser.tabs.remote.warmup.enabled: set to false. I might accidentally added this to my 56.0.2 (and set it to false) since I don't remember tab warming being in pre-Quantum, but my 69.0.2 has this and I set it to false. There is also a thing with mouse cursor hovering over a tab making it reload the tab, but only after Firefox clear my cache.


If any of you curious about why I'm using 56.0.2, it's because I'm still using Multi Paste and Go add-on, which is a Godsend to me. It's really helpful with accessing or opening several links or images at once, oftentimes more than 30-40 images, and unfortunately the add-on is not made compatible with 69.0.2. I'm a very careful person when it comes to security and I never opened any sites with questionable or suspicious quality, just things related to work (photography) and bills (So-Net Nuro, Softbank, etc.) so please don't worry about my browsing habits or security risks. I also always disable Flash plugin.

At this point, I really have no idea how to prevent Firefox from clearing my cache. Sometimes Firefox clears my cache when I am still browsing, sometimes when I leave it idle. Sometimes I can reach over 1 GB of cache size before Firefox clears it, sometimes Firefox clears the cache when the size is still about 100-200 MB.

I always perform system maintenance manually (from updating OS to installing drivers, from setting up Adobe Photoshop and Lightroom to making backups) so I'd rather clearing my cache manually instead of letting Firefox do that for me.

Can any of you help me with my problem with cache?

I appreciate and thank for the help, advice, suggestion and assistance you could provide. I don't mind using custom userChrome or userContent as long as you don't mind guiding me with it (I never used it before).

I'm looking forward to get your help and feedback. Thank you very much.

I've read this thread which has the same problem - https://support.mozilla.org/en-US/questions/1114674 - but the solution here is just to click 'clear cache' twice - this does not work for me; I've clicked it twice, 3 times, 4 times - it still will not clear. Can anyone please tell me how to fix this bug? Firefox is constantly freezing and working slowly & I think the full cache may be part of this. Thanks
