For the past month or two, at random times when I open Firefox, I see a message stating, "Looks like you reinstalled Firefox." To be clear I have not uninstalled Firefox in any instance where this message has been displayed.

When this happens, I’m unable to browse the web. To resolve the issue, I have to remove the uBlock Origin extension and reinstall it. Once I’ve done that, browsing returns to normal. However, I then need to reconfigure my filters and adjust settings within FireFox

I’ve tried uninstalling and reinstalling Firefox to see if that would prevent this issue, but it hasn’t worked.

This problem is specific to my PC—it has never occurred on my MacBook.

Any assistance in understanding why this happens and how to prevent it would be greatly appreciated.

Thank you.

Hello Team, I am trying to install extensions to my Firefox on Macbook Pro M3.

Getting error in the subject

An unexpected error occurred during installation.

Extensions I have tried to install so far: AdBlock for Firefox by AdBlock uBlock Origin by Raymond Hill

Both are failing with the same error.

I have tried reinstalling Firefox, Private Window, nothing helped. It did work for me with Firefox on Macbook Intel

Unable to view YouTube comments using Firefox on android. I can view the comments on Opera, duckgo and chrome.

This problem started about four days ago. Comments show on the short videos but not the regular videos. When I tap on "comments" the resulting page/frame is empty.

When trying to open sites from my email, such as usps.com, I get the following message and it will not allow me to open it even if I put the address in myself:

Hmm. We’re having trouble finding that site.

We can’t connect to the server at tools.usps.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

PLEASE help me find this problem. Until the last update, I didn't have this problem. What do I need to do? Thank you

I don't know where to add shortcuts all at once instead of adding each one individually, I tried to search for a "shortcut folder" within the bookmarks manager and i found nothing, is there anything I can do to move opera browser's speed dial bookmarks into firefox shortcut

I signed in to be sure to save my bookmarks and i lost them instead. When i hit sync, i wanted to backup my current bookmarks. Instead, I lost them. It reverted to the old bookmarks i had a few weeks ago. I lost all of my bookmarks from the last few weeks. HELP!

Hello Mozilla Team,

I am encountering an issue in my React project where an <input> tag is used as a child of an SVG element. The input cursor visibility is inconsistent: it shows properly on some screen ratios but disappears on others. This issue appears to be related to how the input and SVG elements are rendered in different viewport sizes and resolutions.

Steps to reproduce:

Create an SVG element and embed an <input> tag within it. Test the behavior on screens with varying resolutions and aspect ratios. Expected Behavior: The input cursor should be consistently visible across all screen ratios and resolutions.

Actual Behavior: The cursor visibility is inconsistent. On certain screen ratios, the cursor either doesn’t show or is misaligned.

This behavior greatly affects the usability of such components, especially in responsive designs. I would appreciate any guidance or a potential fix in future updates to address this rendering inconsistency.

Thank you for your attention to this matter. Please let me know if you need further details or a code example to reproduce the issue.

Best regards, Gyanendra Kumar Dubey

I want to copy/clone information in my Firefox Profile (Bookmarks, Logins, ..) from one device to another. Once that was accomplished, then I would enable Firefox Sync for the two devices.

Scenario: Device “A” (Profile A): Primary/Original/Source Device “B” (Profile B): Copy/Clone/Duplicate

I understand that if I set up Firefox Sync first and then sync the two devices what I will get is a combination/fusion of the information on the 2 devices, i.e., all the “good” stuff in Profile A plus all the superfluous stuff in Profile B that I would just as soon ignore/delete – which is not what I want. This issue has been raised in a number of other posts on this forum but with no suitable resolution offered (that I could find). I’m wondering if there might be a “work-around” that would achieve the desired result.

So ... would this work?

1) Back everything up first (of course!) 2) Glean any unique information to be preserved (Logins, etc.) from Profile B and incorporate it into Profile A (Profile A now has everything essential!) 3) Purge Profile B

   a) Create a New Profile on Device B (and delete old?)
   b) Delete everything possible from the new Profile B (default bookmarks, etc.)

4) Login to Mozilla account and enable Sync

The idea is to create a “blank” Profile on Device B so that when Profile A and Profile B are Synched together (combined), Profile A remains unchanged, and Profile B is populated with everything in Profile A (a perfect copy!). The result that I want after Sync is essentially A+B=A, the solution of which is of course B=0, hence the focus on creating a "blank" Profile B.

Instead of purging Profile B as above, an alternate method might be to first “pre-load” Bookmarks in Profile B by the usual method of Backing up Profile A Bookmarks and then Restoring them to Profile B. At this point Profile A and Profile B Bookmarks would be exactly the same and Synching the two devices should make no changes to either’s Bookmarks. Logins and other information would still have to be purged, but this could at least be a head start.

Presumably this idea could be extended to more than 2 devices (but with only one being the “Primary”).

Note that I am (myself) only concerned about Bookmarks and Logins, and am thus glossing-over how other information that might be important to others (Browsing History, Tabs, etc.) might be Synched.

Could someone from Mozilla/Firefox with a knowledge of the inner workings of these features please comment as to the efficacy of this “work-around”?

Thanks.

Hi, recently I encountered a werid popping sound while listining to music on YT. Firstly as I wanted to change my old DAC I swichted to a new one (every reason to buy new stuff is good), but now it is unberable. I spend some hours trying to figure out, watching tutorials etc. disabling all the stuff from device manager, checking if fast boot option is disabled, rolled back drivers, swithed to USB 2.0, disabled all of the extentions etc. etc. (the sound popping was only in youtube, but I figured maybe its due to my hardware or something). However, I found out that clearning cashe works for a couple of minutes, and browsing on incognito tab also works for some time. This leads me to belive that maybe a new updated is somehow messing it up, or google really wants me to use chrome. Any advice would be helpfull. Thanks

Every two or three hours, firefox locks my computer by creating thousands of tracks and temporary file megabytes. I have to power button the computer off and restart.

I have tried ridding of cache etc, but nothing works. I am running win 7 64x ultimate, and the latest firefox browser, but this issue has been going on with previous versions and over years. Yesterday the problem corrupted some files that sfc /scannow can't even fix.

Please help.

I have a typical search bar at the top of the browser window. Recently, as soon as I begin to type a search, the bar expands to cover the whole top of the browser window. How do I stop this from happening? It's unnecessary and irritating. Firefox 133.0, Win 11
