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 ??

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.

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.

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?)

How to configure Firefox so that it will load everything from cache after restart, in case I am offline?

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 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.

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

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!

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.
