Problem: Persistent 150 KB of Cached Web Content For several years, I have gone to “Settings” / “Privacy & Security” / “Cookies and Site Data,” clicked the Clear Data…” button, checked both “Cookies and Site Data,” and “Cached Web Content,” and clicked “Clear”, and consistently gotten BOTH “Cookies and Site Data,” and “Cached Web Content” down to “0” zero. Recently, I have been unable to “Cached Web Content” to go below “150 KB of disk space.”

         I have NOTHING listed in “Manage Cookies and Site Data” or “Exceptions -- Cookies and Site Data.”
         I have tried reinstalling, but the problem has persisted.
         On the assumption that this is malware problem, I have continued to use Mozzella VPN, but stopped using the program for browsing, etc.  Should I stop using it altogether until the problem is fixed?
         Can you tell me how to get rid of the last “150 KB” of “Cached Web Content”?

I'm using a macbook air, and I was trying to use the fingerprint login thing, when instead of unlocking my puter it shut down the whole thing and it started to make very loud fan noises. I waited a few minutes for it to stop, then got back on, and my bookmarks and saved passwords were deleted from firefox. No passwords or logins were reset on any other applications. This is very alarming since I had just made an email and some accounts to manage some event I'm holding, and now the password I trusted to firefox is lost. I need this password, as otherwise I cannot log into my email since I hadn't time to set up recovery measures (I have tried to recover it, but there's insufficient evidence for google that I own the account :/ ).

I tried looking through my browsing history for anything helpful, but everything was deleted from there as well. I also was not logged into my Mozilla account at the time either, so I am really in some sort of predicament here, , I'd appreciate any advice and ideas here!!

I can no longer download pdf's (bills, statements,etc) Downloads come in with "name.pdf.part" When I delete ".part" then I can open file. If I don't change name it reverts to pdf.part extension. It's a pain renaming every download. Please help me, I don't want to switch to Chrome. Thanks!

after creating a new profile, and copying everything in the root directory to the new profile, including search.json.mozlz4, the default search engine setting does not get transferred over and is still set to google

sorry for my bad english. in german I always get in a circle an come never to this page to put in a question. I use version 127.0 and look for in the option to change save file behavior. I already asked google and the comments are from 2022. I like to activate a third button in the save file message box. Currently there are 2 buttons and I want to activate the 3. butten named "save a copy" or like this. I want to choose the directory always self and when I like I want to decide to save a copy with this button and firefox add a copy number automaticaly. I know from google if I do not use the option "always ask where to save file" firefox do so. As background I need this when I use a auto clicker to use a button on a page to download smartmeter data files. Unfortunatly the file have always the same name and not include the date and time. Unfortunatly I am not able to configure firefox automaticaly with the auto clicker or in the crone job file.

Please help an old dummie? I have an existing FF install on a laptop. I would like to clone it (with bookmarks, settings tiles etc) onto a new PC. An article I read said open FF on the PC you want to sync. This is confusing! "Synchronising" is ambiguous, meaning 2-way. (but which way) "copy from" & "copy to" would be clear. I am worried I will synch(copy) from the new to the old....... effectively deleting/wiping out all my preferences in my original install. OR (preferably) Is there a way to just copy the whole installation from my original PC onto a USB stick & installing FF to the new PC from it? Many Thanks

This is my crash report https://crash-stats.mozilla.org/report/index/9ff24288-5f5b-4ad1-ac89-2b1180240805 please help on how to solve this

Basically I just bought a 4k monitor while also planning to use the old 1080p one. As it turns out the default size setting makes the fonts on the big screen too small, or the small screen too big.

In Windows this wouldn't be an issue since I can just use multi scale. Ubuntu has that too, but it weirdly implemented and causes the smaller screens to be kinda blurly. The accepted solution is to use Wayland but it causes everything to be unbearably slow to me so that's out.

Not expecting such an odd use-case to have an implemented solution but I'm eager to be surprised.

Fairly frequently I need to send files I receive in .txt or .pdf format to my browser to read.

I have attached hereto two versions of the same file - one sent to Firefox and one sent to Chrome.

Note that the screenshot of the Firefox version of the file contains loads of UTF-8 character translations that are incorrect and show up as strange characters instead of letters or punctuation marks, while the same file shown in Chrome is almost perfectly clear.

I am running Firefox version 127.0.6533.89 (64bit) in a Win 10 Pro 64 bit environment that is up to date as of August 1st.

This has been a problem with Firefox for a very long time and I would like to know if I have misconfigured a setting that has caused this.

I'm using openSUSE Tumbleweed and KDE Plasma. Ever since I updated to Plasma 6.1, Firefox crashes constantly when using Wayland. I'm not having this problem if I'm using X11. Crash reports are sent after every crash so I'm sure someone can reference these. When starting Firefox from a console, I got this message after a crash: "[GFX1-]: Wayland protocol error: wp_linux_drm_syncobj_surface_v1#67: error 5: explicit sync is used, but no release point is set"

Will this get fixed with the next Firefox update? Currently using 127.0.

Firefox keeps going off for from 5 seconds to about 20 seconds. It happens several times a minute. The screen goes blank and I can’t click on anything. Really aggravating. I would appreciate any help. Thanks

Everytime I load Firefox the bookmarks sidebar is not shown.

Navigating thus View => Sidebar => Bookmarks I can bring it up. It will stay visible for the whole of my browser session. However, after I've closed this session and started another. the bookmark sidebar is missing again.

How can I make the bookmarks sidr be available all the time?

FF 127.0.2 OS Windows 11 Pro v 24H2 Build(26100.994).

How do I stop these recurring update notices? Every 3 seconds. I'll update when I am ready as this current one does not affect me at all. For a while I fell for it, stopped what I was doing and did the ridiculous update, it still continues! I can move on to a different non-Mozilla browser if I have too. Return the option to not update and/or do it manually. FF127.0.2

I have the strangest problem. If Firefox is closed and I do a speedtest in another browser, download a file, or do other internet activity I'm getting about 200-250Mbps d/l and 100Mbps upload. As soon as I open Firefox, whether I load a page or not, the upload speed stays the same, however the download speed drops to about 25-50 Mbps. This only happens on one PC, the upload isn't affected, and resolves itself as soon as Firefox is closed. Here's what I have done without any change in this behaviour;

• Rebooted
• ipconfig /release /renew /flushdns
• Removed and reinstalled the network adapter
• Enabled, disabled windows auto tuning and tested (slower disabled)
• Updated Windows
• Refreshed Firefox
• Uninstalled Firefox, deleted remaining folders from Appdata (Local, Low, Roaming) as well as the program file directories and "Mozilla" registry entries. Restarted and reinstalled. Issue immediately resumed when Firefox was open.

Also when connected to a VPN Firefox download speed increases to about 60Mbps and is consistent across other software. If I split tunnel another browser outside the VPN, it is still stuck at 60Mbps. If I close Firefox the speed increases.

This makes absolutely no sense to me, so I'm hoping someone can shed some light on this - but it does seem to be something Firefox is doing.

Thanks for any help anyone can provide.

For the past couple of weeks I have been getting the "Hmmm, We're having trouble finding that site" error screen quite often from both searches and links from other sites. It's always happened once in a while but it hasn't been anything bothersome. However recently it has become quite bothersome because it's happening a lot! However not all the time. It's not completely broken, just mostly. And it's happening while trying to visit sites that I know and visit frequently such as Amazon, Ebay, and even sites for local businesses that I trust and know are working. I'm not having any internet issues with my home wifi, nor am I having this issue with other browsers. I have however also noticed it on my Firefox mobile browser as well. I posted about this a few days ago and got some email back about an issue with my post. If this happens with this one and I'm unable to get this resolved I will just get rid of Firefox on my devices. FF has been a long time favorite and is usually set as my default browser but if stuff like this is going to continue, I can change that real fast. There are plenty of other browsers that work just fine and have decent customer support.
