What's up with this? Two fake Trust Wallet add-ins were disabled within the last couple of days after one stole my money and I reported it, and another similar one. They had been pinned to my toolbar and they were subsequently taken off from there with the message that they had violated Mozilla's policies. Now I see that again there are two of them. How can this be prevented? The most obvious sign that these are fake is when one goes to create a new wallet the add-in directs the user to import instead, i.e. it wants to steal private information like recovery phrase.

Hi - Firefox placed an 'Old Firefox data' folder on my desktop and I am unable to delete it. I'ver tried third party apps, logging in as administrator, command line delete, uninstalling FF but am still stuck with it and my network settings are wrecked so I can't re-establish connection to the internet on that machine. Anyone with any suggestions as to how I get rid of the 'Old Firtefox data' folder ? Many thanks...

Every time I open a new site or webpage, the automatic translation window pops up. I don't need translations and I have to choose "don't translate this page" again and again. I've searched everywhere on Firefox and I can't find a way to stop this. It is extremely intrusive and annoying. I don't understand why Firefox should decide for me what I want and what I don't want. Has anybody solved this problem.

hello. i downloaded firefox from official void linux repo, and have issue with font rendering or smth. in settings option "Allow pages to choose their own fonts, instead of your selections above" is enabled. don't have same issue in any other gtk apps on my system.

I was able to use it this morning from my macbook. But the afternoon I was on sites where my passwords usually fill but now everything is empty, everything had been deleted. I tried to log out and back in to mozilla and sync, but everything is gone. Over 100 sites and passwords. How this happened ? Where can i ask for help since Mozilla doesn't offer any.

I am using Firefox v140.0.1 Snap on Kubuntu 25.04, Kernel 6.14. Since the Firefox update in the past couple days, the mouse cursor has started appearing huge and slightly blurry (as though the image is scaled up) in Firefox and nowhere else. The size is visually annoying, and occasionally difficult to know exactly where I'm clicking (trying to move the caret in a text box for example). It also appears to be a different style from the main desktop cursor, the shape and color are ever so slightly different, but this may already have been the case and I simply didn't notice because of the previously small size. Firefox doesn't have its own built in cursor settings that I can find, nor obey the system cursor settings. I have a high DPI display so perhaps it is being over-compensated for? e.g. both the system and Firefox are scaling the cursor up, assuming the other hasn't done it already, resulting in a cursor that's too big.

I switched my default search engine from Google to Bing. As you can see in the attached screenshot, it should be searching with Bing. But for some reason the search results are always Google. How do I fix this? I haven't refreshed Firefox yet. I was hoping to avoid that.

To sign into my Amazon account, I'd like to enter only my email address and my password.

But I have to enter my email address and my passkey. A verification code is then sent to my email address. I then need to enter that verification code to complete signing into Amazon.

On the Amazon's Sign in page (where I enter my passkey), it says "This request comes from the app 'firefox.exe' by "Mozilla Corporation".

How do I disable the two-factor (aka two-step) authentication for Amazon in Firefox?

latest versions of firefox (now at 140.0.1) keeps opening onto my 2nd monitor which is off - how to stop it doing it. Tried making new profile which works for awhile, but sooner or later they all bump it to the 2nd monitor and it never comes back - tried moving to primary and closing it there, but next time back on #2. Open 2nd window while first is on primary, and that goes to 2nd monitor...

Every time I make Firefox full-screen, it immediately crashes and shuts down. I have restarted the computer, uninstalled and reinstalled Firefox, but it still doesn't work.

I was finally forced to update my Firefox to the released version. I am increasingly unable to log in to various "secure" websites with Firefox 140...1 although Chrome 106 (old, but can't update) has no problem. There are also a number of captchas that are simply invisible to firefox. Why is this happening?

Connectivity to www.xfinity.com disappeared...with latest firefox 140.0.4 as near as I can tell. xfinity still works on Google Chrome and Microsoft Edge. Please fix firefox browser so I don't have to go to chrome or edge. thanks!

Chrome user returning to Firefox here; I'm experiencing an issue where most pages would take at least 4 to 6 seconds to load, especially for heavy media sites like YouTube which could take 6 seconds for it to be barely usable, and 10 or 13 seconds for it to finish loading. My internet speed is 1gb at most and 800 Mbps at the least.

It loads sites like Reddit pretty fast, like 3-5 seconds interestingly. It's largely YouTube and other sites where the pages load infuriatingly slowly, and Chrome Mask did not helped with this.

Here are the things I did: Refreshed Firefox, started in Troubleshoot mode, installed Chrome Mask for YouTube (Did not work), disabled DNS, closed all foreground apps except Firefox, used a different profile and enabled/disabled hardware acceleration.

Specs: CPU: i5-3570k GPU: GTX 1070 Ti RAM: 16gb DDR3 OS: Windows 10 Hard Drive type: SSD

Final notes, it says I use Microsoft Defender Antivirus but I am actually using Malwarebytes. I also use uBlock Origin which is the entire reason why I permanently switched from Chrome to Firefox.

firefox updated to 128 esr all of a sudden (i didn't click update or download for this) and when i went to open firefox, the appearance and everything changed. it looked like google chrome and none of my bookmarks and settings and layouts were there. they just DISAPPEARED. i tried googling how to to fix this and for some reason every time i search it takes me to another search engine instead of google. (this is beside the main point though). I'm so frustrated right now since all my bookmarks are gone (literally having a breakdown). I tried looking through the help articles and all of them just say to use the backup profiles or that there are bookmarkbackup files in my profile folders or that firefox would download a folder with files from the old version but none of that happened. I looked into my folders for older profiles trying to find places.sqlite files but NOTHING. there is literally NO backups or profiles dated to before July 16 2025; the day it updated (shown in screenshot) and there is NO bookmarkbackup files anywhere. i have signed in to firefox prior and had my devices synced for awhile and no issues so there should have been previous profiles and data saved onto my computer. Please help, I really need my bookmarks back!

Picture Verification is not working in Firefox. It works correctly in Chrome. When trying to access prosper.com, it continues to send a link to check pictures. When clicking on the correct pictures, it comes back a repeats another picture.

Why on earth would you remove the ability to select move multiple tabs anywhere in an open window browser???? Until recently, I could select the first and last tab, hold shift and move them anywhere I chose. Now that feature doesn't work at all. It duplicates one tab or I'm given a choice to move to the front or last of all open tabs! Please give me the feature back!!1
