For the past few weeks, Firefox has started crashing when logging into various websites. I've updated Firefox, cleared cookies etc, reinstalled Firefox, opened it in Troubleshooting mode, updated my OS, disabled extensions... everything I can think of. After some sleuthing, it seems to only happen when trying to log into a website. Doesn't happen on every site, which is weird.

This is so frustrating, please help!

Currently I'm using the css from this thread https://support.mozilla.org/en-US/questions/1341968 Now with firefox 113, this no longer works, I'm hoping someone can help me with this.

Please excuse me if I miss any details.... this is my third time trying to submit this issue.

I will just skip to the meat of it this time. I'm getting this error while working from my localhost. I have been working on a personal project for years with this set up with no issues until today. I can no longer click on the errors in the console log and be directed to the Debugger tab. When I click on errors, nothing happens. If I try to open them in a New Tab, I get the error below:

The address wasn’t understood

Firefox doesn’t know how to open this address, because one of the following protocols (webpack) isn’t associated with any program or is not allowed in this context.

   You might need to install other software to open this address.

I have also noticed firefox does not even load all the files until I refresh it at least twice. Even when it is all loaded properly, the error persists.

I have tried: - restarting firefox - restarting my computer - clearing ALL cache and cookies - running firefox in safe mode - disabling all add ons - disabling performance mode (was already off) - checking network.protocol-handler.external.javascript = false (it is)

Let me know if there is any other information I can provide. I really dislike having to work in chrome for this so I hope I can find a solution as soon as possible.

When I type about.config in the address bar, I just see search results for it, instead of going to the config page. I tried enabling a separate search bar in settings, and also turned off all suggestions, but that did not help. I still see the spyglass search icon on the address bar. How do I get past it?

I am using Firefox Developer Edition in a work environment that only saves directories between weekly restarts by explicitly managed rules. As a result of some missing folders from my weekly restarts, I need to sign in to my Firefox account and enable sync each week. Currently my machine retains the %APPDATA%/Mozilla and %LOCALAPPDATA%/Mozilla directories + children.

What other directories are needed by Firefox Developer Edition in Windows to retain the user profile/syncing, et. al.?

Thank you for your time!

Hi,

I seem to having multiple problems with Firefox over the last few weeks...

This problem is - I can't unblock popups. I have got popup blocking enabled, with a couple of Exceptions - it's been working fine until I wanted to use it today. I have tried turning off popup blocking, re-entering the exceptions - nothing is helping!!!

Does anyone know what to do?

Thanking you Pedro

Hello. My laptop died and according to IT is "gone". My hard disk however can still be accessed. I was able to access my firefox profile data from the old hard disk, and I was able to find the two firefox password files (key4.db and logins.json), as described in https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data. However, when I use the procedure described in https://support.mozilla.org/en-US/questions/1416465 to import the passwords on my new firefox on my new laptop, it does not work: firefox tries to look for a csv file, but there is none: I only have the "raw" db and json files, because i never had the opportunity to "export" my pwds as a csv file. Is there a way to import pwds from one version of firefox (the one running on my dead machine) to another copy of firefox (the one running on my new machine), if those pwds have not been previously "exported" as csv files by the "original" firefox/machine? thank you!

We try to deploy Extension Management Settings via GPO.

Goal is to allow only whitelisted extensions, but don't block themes, dictionaries and locales.

Below find the JSON-settings deployed to the client, which should allow all themes and whitelisted extensions. Unfortunately this blocks everything except whitelisted IDs. See example screenshot with error-message, when trying to install a theme. We don't want to whitelist locales or themes, they should be still allowed for installation.

What I'm doing wrong? - Thanks for your feedback.

When I right click a tab I do not get the option to "Send Tab to Device" that I am used to on Windows. Is this missing from the Linux version? Or is there a setting for it?

I have searched the internet for this problem and could not find such things. I would appreciate any help!

Over the years I have accumulated important links in my Firefox Bookmarks bar and passwords file and it would be a disaster if for some reason my hard drive got compromised and I could no longer access them. Is there any way to copy the data to another set-up, independent of my laptop, from where the data could be retrieved in a usable form for display on another laptop or PC? Thanks.

On 112, I had my css set up to make the status bar hidden and only show the url path when I moused over it in the lower left corner of the window. It also cut itself short to only the length of the url similar to the www.wikipedia.org box in the attached picture. After upgrading to 113, my browser has this black bar at the bottom. When I cleared out my css file, urls would show up in the bar when I moused over them. I've tried a few different css fixes but none of them will get it back to how I had it working in 112. The picture attached is what I'm getting in 113 right now with the css below. the black bar below the mouse over url goes all the way across the window and is always visible. Here is my current css file:

I'm using Firefox 113.0.2. I want to export my logins and passwords, but when I click the 'export' option, a Windows Security window opens asking for my Windows login. I don't have a Windows login set (no one else has access to my PC).

According to Firefox's own info, if you don't have a Windows password, the dialog asking for one shouldn't pop up.

I can't get past this and I've googled everything in sight. Does anyone else have a solution to this?

Thank you! Averill

I been having problems with firefox using up most of my cpu while browsing some websites and it doesn't even load as fast as before. This has been happening for a few days now. Prior to this, firefox was fine and loading pretty quick, but these last few days have been painful.

Thinking that was a small bug, i restarted my computer. Before opening the firefox again, I opened up task manager to check how much resources will the browser be using. Before that usage would be normal and not even close to high, but opening firefox and waiting a few seconds to let the home window appear, the task manager showed that it was using all of it still.

I browsed some other help questions on this website and disabled "Use recommended performance settings", because that was one of the solutions on one of the relevant questions. But even that didn't do reduce resource usage either. Is there any way to fix this or will I have to suck it up and suffer with slow loading?

Hi,

I've imported around 200+ passwords from another web browser as '.csv file' in Firefox from option of 'import from a file.'

During the import, I was logged into my Firefox account as well.

But, after resetting PC, I downloaded the Firefox and logged on with my Firefox account, and there are only 29 passwords showing up, rest of the passwords are not there.

And, now I do not have access to that .csv file as well.

I am on Windows 11 and had reset my PC with option to 'Keep My Files' so there is no data loss as per my side or on the hard disk drive.

Please help me to get those passwords back. They are extremely important to me.

Thanks in advance!

I have adblocker plus and is not blocking my facebook ads. (I am using it on my iMac). So I removed it, then reinstalled it and it still does not block the facebook ads.

I tried refreshing firefox 3 times but it got stuck in the "almost done" part and I had to quit firefox each time since it would not complete the process.

What else can I do?

Thanks, Martha

Hello:

I have 2 profiles in use. 1 for personal use with their respective bookmarks, passwords, and extensions, and I have no trouble syncing with this one. However; profile 2 that is for work use that has its respective bookmarks, passwords and extensions, has become a nightmare.

It happens that I have both profiles on the same computer and when trying to create an account in Firefox, the system asks me to enter the email registered in profile 1, with the warning that bookmarks, passwords and extensions will be mixed.

I mention that I have migrated from Google Chorme to Firefox for speed reasons and because I use windows 7 (I don't like later versions) Now well; in Google Chrome you could create as many sessions as were registered but in Firefox you can't.

Oh! I have been working fine with Firefox but suddenly an error occurs (it has happened to me 2 times in the last 2 months) in which the program closes and all the data of my profiles stored on the pc DISAPPEARS or is deleted (including cache), when I want to open them again:

firefox.exe -P

Then I have to give myself the task of synchronizing profile 1, but profile 2 I have to be importing from my previous Google account or importing a backup Bookmark.

The option to copy and paste the data from Firefox to replace it in the path (supposedly brings with it the data of everything):

C:\ProgramData\Mozilla-1de4eec8-1241-4177-a864-e594e8d1fb38\updates\308046B0AF4A39CB

with Firefox turned off it has not worked for me. Since when opening I see 2 profiles called Default "X" and Default "Z" without data.

This is a headache that if it happens to me, it happens to millions who have 2 or more profiles.

Why can't I sync a second profile? Why do you insist that there can only be one sync per device? Is there a solution for this?

Note: I have read all the tutorials out there and the situation remains the same. Synchronization with 2 or more profiles is never described.

Thank you very much to whoever asked this question!

I just upgraded firefox to v 113 64 bit with windows 7 ultimate. Now when I watch youtube in fullscreen there's a border around the screen. i don't use picture in picture and it isn't on yet the border won't go away no matter what I do. Please fix this or i will use another browser. i will include a screenshot from youtube in fullscreen mode look at it.

Why does Firefox automatically save tabs? It is annoying to have to delete them every day... I want the option to NEVER save the tab and close them all when exiting

On one web site (see attachments), my location is being detected as being outside USA while using firefox desktop browser, yet on the same computer, my location is being correctly detected as being inside USA.

You will see the asian words. When I change the pull dawn tab ("Saudi Arabia") to "USA", the asian lettering does not convert to English.

Not sure how to fix this.
