After an update, Firefox messed up my toolbar configuration. After resetting everything back to normal, just one thing doesn't want to stay where it's placed: the "new tab" button a.k.a. the "plus sign". I want the button to be to the right of my open tabs (screenshot no. 2) but after closing and opening Firefox again, the button simply jumps back to the left (screenshot no. 1). So I go to (Right Click) > "Customize Toolbar..." > (Drag the button to the right) and it works, only until I restart Firefox again. Is there anything I can do to make my changes stable?

(One more thing: there is this "List All Tabs" button, which can't be removed, how could I remove it?)

Firefox Version: Developer Edition; 132.0b3 (64-bit); aurora update channel

I've just transferred from one Windows 10 install to another, and wanted to transfer my Firefox profiles along with me. Initially when I transferred over my main profile, the addons worked at first but broke after a short while (specifically there were still as many addon buttons in my toolbar as before, but they were all blank and did nothing), and wouldn't restore after shutting down and reopening Firefox. At first I tried disabling and reenabling each extension, and that worked, but after shutting down and reopning Firefox, they were all broken again. I looked for fixes and tried the solutions in this ask: https://support.mozilla.org/en-US/questions/1260445; first, I tried jscher2000's solution of "deleting" extensions.json by renaming it, but it only fixed a couple addons (BitWarden and uBlock Origin, mainly). Then I tried cor-el's solution of deleting combatibility.ini, and that still only had BitWarden, uBlock Origin, and maybe one or two others working - it also seemed to slightly further the problem, as the toolbar was now set to default without even the blank addon buttons, and the extensions overflow button now just opened about:addons.

But, then I deleted the profile and copied it over again, but this time I preemptively went into extensions.json and changed all the paths to the new correct path (I also did so for the one path address in pkcs11.txt just in case, because it was the only other thing that came up in a search in the profile folder that had that hard-baked full path that might need updating; I don't know what pkcs11.txt does but I just wanted to be sure), and then (not sure if this part matters quite as much) did Create a New Profile and selected that existing copied-over folder as the folder for that profile to use. Lo and behold, all my addons worked! And they've continued to work as normal and not break through several times of closing and reopening both that specific profile and Firefox overall, and even with a couple shut downs and restarts of Windows.

However..... I tried doing that exact procedure (copying over profile folder, editing the paths in extensions.json and pkcs11.txt to be the new correct ones, Create a New Profile and selecting that folder) for my secondary profile, and yet still most addons end up nonfunctional with a defaulted toolbar and extension overflow button opening about:addons just like in the main profile after I did the compatibility.ini fix (even though I didn't even touch it on this profile). After several tries of doing that with differences in naming of the new profile, or also trying to delete compatibility.ini, still I got the same result. Then I tried doing the "disable and then reenable each extension" thing again like I tried first on my primary profile, and it brought the extensions back and in their correct order in the toolbar, but when I exited Firefox and reopened it, they were back to the multitude of blank buttons (which, at least, was a change from before). I have no idea what's different, as far as I'm aware I'm doing the exact same thing that worked on the first profile yet it's still ending up broken.

I've also now tried copying over a third profile in the same manner, and it works perfectly just like the first/primary profile did. But the second profile still just will not work.

Hello,

This has been very challenging for more. I have searched the internet forms I cannot find the solution to this issue, please help! When I first bought this computer I tried to install Firefox it crashed and said that there was another instance of Firefox running. Now I tried again to reinstall Firefox and I am getting a new error, which is: Your Firefox profile cannot be loaded. It maybe missing or inaccessible. I followed one of the forms on this site. I did all that was in the form, IE: I tried to recreate profiles through the profile manager. I also tried to clear the cache in the cache folder. I also tried to move the profile folder via the profile manager. Nothing has worked. Please help me I am very disparate. Also so if necessary is there a way to get live support. thank you :)

I had a background image for the new tab page that has suddenly stopped working, it just displays a white screen. I clicked the 'reset to default' button next to 'Wallpapers' on the new tab page to try to fix the problem but nothing happens. No wallpapers show up under that section either where it used to be when it was working. I've restarted Firefox and the same thing happens. I have not enabled any third party CSS wallpaper.

Apart from that, everything else is working as it should. I'm sort of a computer-idiot so if anyone could please use layman's terms it would be very much appreciated!

I've been seeing this more and more, but my toolbar will change by itself every restart. The add tab button will shift all the way to the left or not appear, the bookmarks won't appear, etc. I'm not sure what can be causing this, and I saw no way to "save" my current configuration other than pressing the done button upon using the custom toolbar, which I had done every time prior to fix my configuration. Does anybody know why this is occurring, and a possible fix? Thank you

Since the recent update to Firefox 131, I can no longer use the Billpay option of my TD Bank account. I am able to log into my account without any problems and use all of the options except for Billpay. I want to add that I know I am not alone with this problem as I have seen several others with the same problem but with different banks. It is the Billpay option which no longer works.

As I said, the bank site is fine until I click on "Billpay", Then I get this: begin quote: "Why can't I access Bill Pay?

I have disabled uBlock Origin, Enhanced Tracking, tried Private Mode, Troubleshooting Mode to no avail.

I have also cleared cookies & data. This appears specific to v131. Any suggestions??

Yesterday I was able to see www.wowpresentsplus.com videos without a problem, but today I'm getting the next error:

Unable to play video. Please try again in a supported browser.

I have the latest version of firefox. I've cleared the cache and so on. Any idea on how to solve this?

The Support forum is full with people having this problem and it seems no one at Mozilla can even b.u.t.t in with something like "we are working on it" or "here is how you can fix it yourself, also for none nerds" or anything?? Hello Mozilla, are you still alive or should we move on to a browser that does not malfunction on such an important issue as copy and paste? P.S. no answer is an answer too Mozilla, we can safely assume you are now buried on boothill, right?

My firefox browser froze and i accidentally sent the crash report. Is there any way to request it to be removed i cant find any form or email to ask for deletion.

Thanks in advance for all the answers!

First of all, why are there two Other Bookmarks folders? When I add a new bookmark, my routine is to open Manage Bookmarks, drag the new bookmark to the second (lower) Other bookmarks folder, then choose Sort > Sort by Name. I have also tried A > Z Sort Order. The sorts work within the Manage Bookmarks window, but they are not saved automatically, and I do not see a way to save them manually. Also, if I go to the Other Bookmarks folder on the far right side of the Bookmarks Toolbar, I have to scroll down to the bottom of the list to see my new bookmarks. They are not in ascending alphabetical order the way I want them.

After Firefox updated my browser version to 129.0, my username and password no longer work on my credit card website. I contacted tech support at the credit card banking site through a live phone call. I told them about the upgrade and also that I can use Firefox on my iPhone to login successfully. I don't know what version is currently on my iPhone but it does work there. This problem is specifically on my Mac Mini. I also can login using same password and username on the Mac through Safari. Their tech support said the problem is with that version (129.0) Firefox web browser. What say you? Thanks.

I have about 30 user/password accounts logged when I use my Firefox account on Windows PCs but here on my new Apple Mac tablet, I do NOT see/get any of those accounts. Is there something I need to do to enable this to work?

After a windows update I get the following message when I try to open Firefox: The procedure entry point ?ToLogLevel@mozilla@@VA?AW4LogLevel@1@H@Z could not be located in the dynamic link library C:ProgramFiles\Mozilla Firefox\xul.dll Then I get Couldn't load XPCOM

I tried uninstalling firefox but it just hung. I restored it to before the windows update but still got the same message

Whenever I click my mouse somewhere blank on a webpage firefox will always select some text/image despite being nowhere close to it. This does not happen to me on chrome.

Hey there, I've been using Firefox for 4 years now, and today I woke up to a huge error - I cannot access any site properly or even use it. The internet is working and is not the issue - Please help.

I've found a solution to the blurriness of the emojis, I've put it in the end of this post, in bold ⤵⤵⤵

My problem is that emojis look bad on Firefox compared to Edge_128.0.2739.79. Two screenshots are attached of bing.com & a Google Doc (left half of both pictures is Edge, other half Firefox). The problem persists on all the sites to a varying degree.

Steps to replicate: A] Open 2 sites in latest Edge & Firefox on Windows 11 (the examples that I've used in the screenshots): https://www.bing.com/ and an Empty Google Doc. B] In the search field of bing and in a new line in an empty Google Doc, copy the following example emojis (That were inserted using the 'Windows_Key+V' which summons the emoji Keyboard of Windows): 🏀🚕 C] Compare the quality of the emojis rendering between the browsers when unzoomed and when zooming.

I've tried in FF (to no avail): A] Disable hardware acceleration in settings (w/ FF restart). B] Setting "gfx.font_rendering.cleartype_params.rendering_mode" from -5 to 5 (w/ 10+ FF restarts). C] Setting "gfx.webrender.quality.force-subpixel-aa-where-possible" to true (w/ FF restart). D] Using both emoji sets in the "Segoe UI Emoji" & "Twemoji Mozilla" fonts in the "font.name-list.emoji" setting, both sets gave me blurry results (w/ FF restarts). D] Disabling all add-ons (w/ FF restart). E] Setting new Firefox separate clean install. F*] In Windows setting the scaling factor to 100% in Windows->System->Display->Scaling_Factor (w/ FF & Windows restart).

How can the blurriness of the emojis be fixed so to make them crystal sharp like in Edge?

Solution: A} Download Noto-Color-Emoji font from https://fonts.google.com/noto/specimen/Noto+Color+Emoji Ensure that your are getting the full resolution font (which came at ~23MB as of 2024.09.23) B} Unpack the font and install according to the on screen instructions. C} In FF in "about:config" find the "font.name-list.emoji" setting and rewrite its value field to "Noto Color Emoji, Segoe UI Emoji, Twemoji Mozilla" (w/o the quotations marks). D} I've attached a screenshot w/ the result, It is marked w/ the red writing of font.name-list.emoji on it.

I am not able to login into my gmail account. Whenever I try to sign in, it shows the message as shown in the attached image. I have tried clearing all cookies and cache. Also removed all the extensions to see if it fixes it Please help me. I have Linux Mint 22 Cinnamon Firefox version 131.0.3 (64-bit)
