It seems that the bookmarks function and history files are possibly "in use by another app". I do not understand much of this. I think it happened after an update. I tried a restore point. I deleted the Icons file as it seemed that might be an issue and they would automatically update on restart. I called Dell support, they could not fix it, neither could my smart, younger friends. So after hours of frustration, I had to install chrome, which I hate. What I want is for someone to just fix it. Its 2:30am and I need to get some sleep, I will check this tomorrow afternoon and see if I can get anywhere. Good night all!

i re-installed my windows, installed firefox, and it automatically re-synced everything, a few days later, windows had an issue so i had to install windows again, but this time, when i installed firefox, i logged in, and after finishing syncing nothing was there, everything is gone, that being said, it's only form the desktop browser, i still have all my bookmarks and passwords on my phone's firefox, but they wont sync into the desktop one i cant find an option to export the phone ones into a file to import in the desktop app, i need help

Just as the summary says, Used to have an icon that I put under the "hamburger" menu on the bookmarks toolbar that opened the bookmarks menu. Can't remember how I got it there. Can someone help me get it back.

Firefox fails to download any files. I've asked for help before, but did not receive a response. Files download well when using MS Edge. Using Windows 10 and latest version of Firefox. Help please.

Hi, my PC had some hardware problem and al its data was wiped as procedure, so i had to install everything from zero, this includes Firefox, and when i did so i did the same as usual, download it, open it and log in to sync my data, but there seems to be a problem, all my data is gone, it says its synced and i try to sync it many times, no bookmarks, no extensions, no passwords, nothing, this is my only account too. tried to look up solutions online and saw people talk about 'old Firefox data' folder that can appear on the desktop but nothing for me, tried to go to about:profiles and see what profiles i had and switch to see if its in any or if the folder appears but still nothing, i don't seem to find a solution, i only got the PC back at the end of December last year, and its as far as i can see my Firefox activity here, but I've always used this account and I've synced in multiple PC's with no problem i don't understand what is happening now. thank you

I have been using 1Password 7 to manage my login credentials. It includes a Firefox extension to fill in account names and passwords in login alerts and pages.

Firefox 147.0.1 (macOS aarch64) in January 2026 has broken 1Password 7's ability to fill in account names and passwords.

To reproduce: 1. Install 1Password 7 Version 7.9.11 (70911000) and its extension version 4.7.5.90 in Firefox 147.0.1 on macOS. 2. Visit a URL for which 1Password 7 has login credentials. 3. Click on the toolbar icon for 1Password 7. A 1Password 7 dialogue box pops down from the icon, containing the username and password for that URL. 4. Click the Autofill button in that dialogue box.

Observed behaviour: 1. Username and Password fields remain blank.

Expected behaviour: 1. Username and Password from 1Password 7 appear in the Username and Password fields.

For approximately the last three months, there was a partial failure similar to this. 1. 1Password 7 popdown dialogue moves from the toolbar icon to the Firefox tab for that URL. 2. Username and Password fields remain blank. 3. Workaround: click in the username field, then tab 2-4 times to further UI objects in the login credentials form. Then click the 1Password toolbar icon, then click the Autofill button in the popdown dialogue. Then, the Username and Password from 1Password 7 appear in the Username and Password fields.

The expected behaviour occurs for the same URLs in Safari.

Thus I suspect that Firefox has somehow changed its behaviour in the last few months to cause this regression. I have not changed the 1Password software versions in this time, because I am intentionally using a previous version of 1Password.

I am looking for a fix or workaround which works with my current 1Password software version. I am not interested in a solution which requires me to upgrade to the current version of 1Password. (The current version of 1Password imposes a feature which I am resisting.) I realise that this reduces the chance that I can persuade the Firefox team to find and correct this regression.

There seems to be a glitch that I keep encountering when trying to sign in through my TV provider, particularly Verizon, to watch DisneyNOW or TCM or any other service for that matter. The website known as "ssoauth.verizon.com" seems to keep hanging on the message "Please wait - we are verifying your account," and the sign in never gets completed. I already tried clearing my cache and history but with no result.

Even trying to submit troubleshooting information is causing the form to crash here. If you would like, I can send you a text file containing the log I saved from the browser console.

I don't like to use the address bar to type searches. I like using the SEARCH BOX in Firefox's New Tab instead. But, with each update, I once again have to try to figure out how to set Firefox searches to be typed in the search box. Is there any way to set this so it doesn't get changed with every update?

I read online that Firefox is planning on implementing AI features. Given the track record of AI in other browsers leaking private information, bogging down connectivity, and generally being a nuisance towards users, I was wondering if there will be opt out features in future updates? Or know of forum threads that will update with tutorials on how to turn off AI features?

If not, does anyone on this forum have recommendations for no-ai browsers?
