Firefox Support Forum

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

I am unable to open Gmail in Firefox. This has only just occurred - until now it has worked perfectly. On trying to open Gmail I now get the following message.

"Corrupted Content Error

The site at https://mail.google.com/mail/ca/u/0/#inbox has experienced a network protocol violation that cannot be repaired. The page you are trying to view cannot be shown because an error in the data transmission was detected.

Please contact the website owners to inform them of this problem."

No other site has been affected, and I can still open Gmail in Internet Explorer, {but I prefer not to use IE for emails

Any help solving this would be really appreciated

I am using version 40.0 with SHA512: 84228c5e70b0ca4b3a8444007691a06cac1ecb6d81995d11a225e6e29dac6799267ebfe60488d0934e32567599c6a4ef0f849dfddbbfd3abdf0b0282599f10c3 If your view youtube (https://youtu.be/BKgzITHwU_k) It's called "Firefox 40.0 for the Mac OS attack" you will see I disabled add-ons, cleared histroy and cache and a refresh Firefox (which I beilive returns Firefox back to default) the Email account for AOl still was maintained in Firefox.

I believe this is a hack designed to prevent clearing of cached information. It may be related to a process called "imagaent" which is related to a facetime application which i don't use. Does anyone have a explanation as to why the AOL email was maintained ?

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 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.

Win10 and FF75. Not at closing (this function is disabled), but at startup. This can be seen in about:cache and the size of the folder allocated for disk cache. Is any setting responsible for this? Is this normal or is it something I did?

Hello, Since v80 cache is completly buggy. It don't refresh pages when it changes. For me it's a bug and many of our customers working with Firefox have the same problem.

Working in websites backoffice (Joomla, Prestashop, etc ...) is now almost impossible ! We have to use CTRL-F5 each time we load or relaod a page ...

Is Mozilla technical team aware of this problem ??

Seem to be new folders popping up here since Firefox 42. What actually is being stored here? I know it is not standard cookies or history. What controls what is allowed to store here?

profile\storage\default folder...

Thanks.

I could not clear a cache, so I checked about:cache and clicked "List Cache Entries". I found the cache that I could not clear had "Pinned" in Pinning section. I searched about Pinning in about:cache, but I could not. I'd like to know in what case a cache becomes "Pinned".

After starting my Firefox 80.0 it is gracefully restoring all the old tabs (which were open, when I closed FF the last time). ... After clicking on one of them, i.e. the weather forecast, it loads the old content of the page. So I always have to reload the page to get to today's weather.

Is there a way to get FF to load the up-to-date-content?

Everytime I open sites like https://developers.google.com/maps and http://ruby-forum.com, and some other sites that I can't recall now, I get "Corrupted Content Error". The send.firefox.com even fails to load. I have to press "ctrl + shift + r" to reload the site, but when I am redirected to the sites (say after login), I can't press ctrl + shift + r.

Removing cache and cookies didn't help. Chromium loads the sites just fine.

Since beta update, I can't clear cache below 1MB.

Clear cache has been problematic for too many versions to remember. It has never held this much memory. I have had to cleanly installed each FF version since at least v45, although it has probably been longer. Why am I having so many problems with installations?

Screenshot from yesterday.

Thank you.

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.

hey my cache always says its full even if i just emptied it if i go to settings and look its not even a full to 10% restarting the browser and the PC does nothing and i get annoyed by the warning message by now

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.

p.s. while I can read English, I'm Japanese and I can't speak or write English fluently like a native speaker, so please forgive me if there's any typo or grammatical error in my explanation.

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!

I have two web pages that I go to on a regular basis. However in the past 3-5 days when I use Firefox the page comes up, but it has old data. I have deleted the cookies and I have cleared history as well, but it continues to come up with the same information... only on selected websites. when using explorer I am able to access those pages and the information is current.

I have been unable to clear the cache for several months now - I click on 'clear cache' in Preferences, & it just reduces by 1MB. 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
