The question has been edited after doing further testing on the issue.

During the last week or so I have encountered the issue that one or more of my Firefox profiles keep resetting after every update.

I noticed there's couple of threads with similar issues already but the generic profile restore instructions are not helping at all since it seems that Firefox is actually wiping some files. I'm not currently sure what causes the files to be wiped, but it's either related to rebooting the PC or starting / closing Firefox. The file deletion also doesn't always hit the same profile either.

I'm running Firefox 150.0.1 for Arch on CachyOS.

I did a clean reinstall of Firefox. After the install I created 2 new accounts in addition to the one that's pre-created on install. All of the profiles work as expected at this point.

The profiles seem to have files in three places

• $HOME/.cache/mozilla/firefox
• $HOME/.config/mozilla/firefox
• /run/user/1000/psd/

The issue seems to be that after a reboot the files under /run/user/1000/psd/ are missing. Both of the other locations seemingly are unchanged but under $HOME/.config/mozilla/firefox the linked files claim no target in /run/user/1000/psd/ is found.

When looking at the missing files, it seems that in total 6 folders have been wiped at the time of testing. All of the wiped directories were ending as ".Profile 1" or ".default-release". Directories ending with ".Profile 2" or ".default" were still there. At this point I'm not sure what is causing this but it seems to explain why the profile is inaccessible.

Manually restoring the files under /psd/ seems to fix the missing profiles completely.

Hello everyone.

I've been having some issues with Mozilla lately. I don't know if my CPU is in bad condition or not but, when I change tabs through my Windows, say changing tabs from Mozilla to Spotify and changing it back to Mozilla, my CPU gets very full, causing my cursor to lag, and Mozilla to be unresponsive for a couple of seconds first and it gets kinda worse as I continue to use my PC, causing the lag to occur for over 10 seconds.

I have seen some similar complaints on the web but they date back to 2014ish times.

What do you think? Is it somewhat my CPU's problem or did Mozilla's handling get worse over a patch or something?

I enjoy Mozilla and don't want to quit using it. Any help would be much appreciated.

Hi everyone.

Basically when the browser is (I think) idle while watching YouTube, FF is constantly backing up (the timestamp in the backup file name keeps getting updated). From the settings page I thought it once every 24 hours. I noticed from higher than normal CPU usage impacting FF and the Windows search indexer. Which reverted to normal once I disabled the backup.

I checked the about config:

• browser.backup.scheduled.minimum-time-between-backups-seconds

Is set to 24 hours (86400 seconds)

But I also noticed:

• browser.backup.scheduled.idle-threshold-seconds

Is set to 15 seconds(!). Is that what I think it is? Back up whenever there's a 15 sec idle window, regardless of the minimum? Can I safely make that 86400 seconds too, or does it do something else entirely?

Many thanks in advance.

Hi All, Apologies if I've missed something, but I can't find an answer anywhere. I've got a fresh install of Firefox version 133 running on Windows 10, and I can't seem to install any add-ons. When I click the install button from the add-on's page, it just sits there with the loading animation and seemingly does nothing for several minutes. Attempting to right-click on the download button, "save link as", and hitting "install add-on from file" using that saved link as another user suggested from a similar problem does nothing at all; there's no feedback whatsoever. The add-on I've been trying to install is U-Block Origin, but I've tried this with other add-ons to the same results. The only other thing I've tried is installing one of the recommended add-ons from the add-on page directly, Privacy Badger specifically. This causes an actual window to pop up telling me Firefox is verifying the add-on, but nothing happens past this point. It just sits there, eternally attempting to verify the add-on with no progress ever made, and no error message ever spitting out. I haven't found anyone else with this exact problem. Hopefully I'm missing something obvious and I can feel really silly about the whole thing soon. Thanks much!

All the Best, G.B.Bari

Good day everybody, I am new to Firefox. I have MacBookAir 11. I added the Ecosia extension since it's my main search engine. I noticed there aren't ads popping up for Ecosia. That is how Ecosia makes money for it's sustainability projects, so, as nice as it is to not see ads, I would like them to show up for my Ecosia searches. I understand you can make an Enhanced Tracking Protection exception (and I did), but where can I find a place to make exceptions for whatever AdBlock software came already integrated to Firefox? I am liking Firefox so far. Thank you everybody. Miran.

The VPN was working a couple of days ago, but now if I switch it on, the browser is unable to use any website. The country is displayed in the bottom left corner as "Australia" even though I set the VPN to Canada.

Either removing certain ones I don't care about or getting ones back I may have already taken out?

I don't see either of those functions any more but I swear there was a way to do it just a month ago.

The Firefox 'Downloads, Save Files To.." location appears to be disconnected from reality. If I indicate either of the Documents or Desktop folders as the preferred save location, both of those folders present as being empty when in fact they both have numerous files/directories. Even if I try to save in "+ Other Locations", those locations are limited to the same as presented in the 'Browse' window of Home, Desktop, Documents and Downloads. Only the Downloads folder displays correctly.

Also as a result of this limited save location, I can only retrieve a file from the Downloads folder (the attached file was saved in my Documents folder but I had to move it to Downloads.

Why does the saving behavior behave like this?

When I have stories (articles) recommended through Pocket on new tabs that I'm not interested in I will typically "thumbs down" or "dismiss" the story. What I have found recently is that causes them to be promoted to me more rather than less. I believe it's interpreting my interaction as engaging with the content rather than not wanting to see it again. For example, I was shown an article on American football three weeks ago and I gave it a thumbs down. Later that day it was three articles. I gave them the same thumbs down. After repeating this process for days, weeks later I'm still getting multiple articles recommended per day related to football. I've never read one out of interest, and I didn't have any recommendations related to sports until the first one I gave a thumbs down. Based on that, I'm convinced it's having the opposite than intended effect. Dismiss doesn't seem make a difference. Please give me a way to tune the algorithm to what I actually want to see, I like this feature and don't want to have to turn it off.

I'm using Windows 11 152.0.4 Firefox version I'm in Australia

I am using Firefox’s new built‑in VPN (not the standalone Mozilla VPN app). When I switch between USA, UK, or Germany, the browser successfully routes traffic through those regions even though the VPN icon remains grey. However, when I select Canada, Firefox appears to accept the region change but no websites load at all. The browser becomes effectively offline.

The following error appears in the console:

Code SearchSuggestionController found an unexpected string value: HTTP error 2

1. dedupeAndReturnResults moz-src:///toolkit/components/search/SearchSuggestionController.sys.mjs:639

fetch moz-src:///toolkit/components/search/SearchSuggestionController.sys.mjs:36 Troubleshooting already attempted:

Disabled DNS-over-HTTPS

Cleared DNS and HTTP caches

Tested in Private Window

Tested in Troubleshoot Mode (Safe Mode)

Restarted Firefox

Switched between multiple regions

Confirmed that USA, UK, and Germany work normally

Only Canada fails consistently

None of these steps resolved the issue.

Expected behaviour: Canada region should function like the other regions and allow normal browsing.

Actual behaviour: Selecting Canada results in:

Blank pages

No network activity

SearchSuggestionController errors

Browser appears offline

Other regions continue to work normally

Conclusion: This appears to be a server-side failure or misconfiguration in the Canada proxy endpoint used by Firefox’s built‑in VPN. The issue is reproducible and persists across troubleshooting modes.

Please investigate the Canada endpoint for the built‑in VPN.

The built in VPN worked great for me for a couple of months, but now whenever I try to turn it on, it starts with the "Get Started" screen, which takes me to a page to confirm my account. When I press continue the VPN button just goes back to the "Get Started" screen & the loop repeats. I've tried signing out & refreshing my Firefox installation but I keep getting the same result. Before it started doing this the button to turn on the VPN was appearing but would not react to clicks.

I can't find a place to manage my payment methods. The only place I found that was when I check out and fill in my information in a store website.

The browser suggests my card and under that it says "Manage payment methods".

When I click that it opens "about:preferences#privacy-form-autofill" and then quickly becomes "about:preferences#privacy".

Please help thanks

Hi,

When I got up this morning, I receved an email that a new device was logged in to my firefox account before an hour or so.

All my passwords are synced to firefox account. I am afraid and want to know what all information is stolen. I immediately removed old devices from accounts page under connected services. However, I see peculiar - 'unknown' device which I can not sign out.

Hello All,

I'm using Firefox (149.0.2 snap) with LUbuntu 24.04.4 LTS. Because of a wrong graphic driver, I had to turn off hardware acceleration in FF.

When FF is started the Initial "Firefox - Choose User Profile" is unreadable (see attached : wrong_screen.jpg), but if I continue (click somewhere in the window) , all the opened tabs are readable.

Once in FF, if I want to select another profile from the application menu -> .. -> manage profiles, then the "Choose User Profile" window is fine (see attached : good_screen.jpg).

I tried to start FF with the "-P" option to specify wanted profile but it continues to start with the unreadable "Choose User Profile" window.

Could someone give me a solution, except finding the good hardware driver for my computer?

Thanks Bouilla.

Widgets had been working well for me up until today, when I discovered that none of the widgets below my shortcuts were loading. In the widget settings, they're activated, but only weather shows up (in the top right corner). What am I doing incorrectly?

I wanted to turn on the built-in VPN feature on my Firefox web browser. After I clicked on the Get Started button, and I signed in to my account, Afterwards, I saw the same Get Started dialog box appear again. Why is this happening?
