Diễn đàn hỗ trợ Firefox

I'm trying to report a rogue version of this add-on, https://addons.mozilla.org/en-US/firefox/feedback/addon/%7B5c474add-03f0-4c67-9479-f32939d7599a%7D/. The actual add-on is fine and works well. Somehow a version, 1.5, got installed and I cannot keep it removed. Whenever I refresh FF, it shows back up. I cannot find any reference to this version on GitHub or on the extensions page. I have uninstalled FF and refreshed it. Nothing works. It keeps coming back. I also looked in the side-install directory, but there were no extensions there. If I remove the extension under the Add-ons Manager, it removes it and I can install it and it installs the correct version and it works until FF restarts and then the 1.5 version shows back up.

I am using the latest Fiefox and i have disabled all adons i have tried everything I have changed my Facebook password every time i g try to share something on Firefox get a black box on the bottom right that says something wrong . I have tried to copy the entire hing but can not i got some of it I have even reinstalled firebox ans still can not share anything I have tried contacting Facebook but that does not happen no response i appears to work in Chrome on a noter Facebook account so it is Firefox. i will send you what i could get on the screen shot the part that is missing s the part that says something s wrong

After updated to Firefox 140.0.4 (20250707120347), all site do not load for me, general sites, like youtube/google. There's nothing wrong with my Wifi/Internet Connection, even Microsoft Edge can load the websites.

If I need to upload a file I click on the OPEN or BROWSE button in the website, Open File dialogue opens trying to list the location it is already looking at, and it hangs for over 30 seconds before listing files. This is windows 11, but it did it when i had windows 10 too. I dont know what to do.

When pasting an image from the clipboard in Outlook Web Access in Edge there's right mouse button option to "Paste as Image". This places the image inline. In Firefox there's no option like this.

Safe mode (troubleshooting mode) doesn't fix this. Ctrl + V or Shift + Ctrl + V doesn't fix it. Shift RMB to get Firefox menu does show Paste and Paste without formatting but it doesn't paste any inline image.

I've attached a screenshot of Edge and Firefox with the Outlook context menu and Firefox context menu.

Firefox version: 140.0.4 (64-bit) Edge version: 138.0.3351.83 (Official build) (64-bit)

How can I download an older version of Firefox ? Version 140.0.4 is full of issues , i.e. slow loading pages that were faster in the old version , shrunk images on some sites , log in problems on others.

As of 7/10/2025, Xfinity Streaming does not open through Firefox. I much prefer Firefox to any other browser so I am a little mystified as to why all of a sudden Xfinity Streaming does not open. I receive my Comcast email through FireFox but when it comes to streaming content, the Xfinity logo just sits there and does not open.

Xfinity streaming works on Chrome and Safari but it stopped working on Firefox a few days ago. Why? I am using the latest Firefox version 140.0.4 (64 bit) and I can only receive my emails. The connection to the streaming service does not open. The Xfinity logo just sits there spinning and no connection. Please fix this. I much prefer Firefox to other browsers BUT....

Hey, So I just updated my Mozilla with the latest update and after I restarted my laptop all my bookmarks, history and favourites are gone. I didn't do any backups manually. It's few hundred important work-related links lost. What actually happened? Can I get them back? Please help.

The TOPIC above is ALL!!! I use AOL for most everything!! I noticed that there would be a "CHANGE", but this looks BAD!!!! I HATE EDGE!!!! I'm 86 and this change is too deep for me. I feel sorry for you folks who will have to FIX this mess. I'm Retired Military & have had this kind of problem pop up.

Hello,

I can't figure out how to add a custom search shortcut, is this no longer possible in Firefox (without installing addons/extensions)?

I recall 'custom search' being more or less ubiquitous, and feel like there was an "Add" button below the Search Shortcuts UI not that long ago.

Bookmarks with keywords would be a reasonable workaround if it weren't for having to prefix the keyword to the search terms.

Thank you, Kyle

Okay, i have been using librewolf for awhile now since i got my desktop fully built. today i went to go search something related to my phone and instead of using duckduckgo it automatically used Google. i do not want this and have no idea how to fix it

Hello, I received an email from you asking me to change my Firefox password for account security reasons. When I changed it, all the data synced in Firefox with my email was deleted. This upset me greatly because I lost important data and saved websites. Please restore the deleted data. Thank you.
