I see many complaints about this new version v 149 for the Mac. The most outrageous one is that you can no longer drag links from a browser page (try BBC) to an email or a doc. You have to copy the link then it won't turn blue and only when received will it show up as a link. Like many others after 30 years use preferred over Safari and others I am seriously losing patience with Firefox. On the very day you announce split screen for Ff windows - you disable a vital feature that has worked for years causing me to waste so far 60 minutes of my hard pressed work time. Maybe this will be corrected in the next upgrade. But I am now intending to avoid all Firefox upgrades for 6 months after being offered. I doubt anyone on this forum will come back on this but my set-up is Mac OS Monterey - and Firefox v 148 worked perfectly before today. I hesitate to try and install the previous version because I am not used to doing such tech moves. Perhaps someone in the Mozilla head office congratulating themselves on the marvellous new upgrade will come across this but I doubt it

I'm running Firefox on Win10 with no options to upgrade to 11. Since the latest firefox update installed, I'm getting a screen that says "Oops, something's wrong," and then I'm kicked out of gmail. A screen asks about sending a report to Firefox, which I check OK for. Today this is happening about every minute to 30 seconds . What needs to happen?

Hello I just filled out a pdf and the font or writing came out blue I want it in black is there some where in Firefox i can get it in black w font or writing please Advise thank you

As the title says, with both with https and http firefox displays this warning:

https://i.imgur.com/MQLsaCk.png

But no way to bypass it, trying to login to my ubiquiti edgerouter at http://192.168.1.1 or https://192.168.1.1

What can i do?

I have to reload history, bookmarks, passwords each 3 - 4 days, when Firefox refreshes the software. It was not happening before, just in the last two moths. How can I fix it?

I recently made the switch to Firefox full time a few weeks ago, and in that time, I have been getting more and more annoying at how Firefox renders Youtube.com.

If I'm on my feed, and I click to watch a video, watch it and go back, I never know what I'm going to see when it goes back a page. Obviously it goes back to youtube.com, but I never know if it's going to load at the top of my feed, or about ten rows down. Even if I click a video in the very first row, and then go back a page, it may or may not load at the top of my feed. I could also actually click a video on the tenth row, and then when I go back, it might load at the top of my feed, though that is not as common, it has happened. It also sort of, kind of, reloads the page when it goes back, but never goes back to the point on my feed at the spot where the video I just watched is, as Chrome and Brave do.

This is not how Chrome or Brave do things, and yes, I know they use a different engine, and I'm sure that's the reason for this issue. Chrome or Brave, if I'm watching a video and click back to my feed, they are much better at loading what is in cache, even if I the video was on the 100th row. I can then manually refresh if I want to.

Hello, I have noticed that using firefox without closing the browser for a while causes the memory to keep rising. It looks like it has a memory leak. After 3 days of watching YouTube I was using 4GB of memory. It was causing Slow Downs.

I have included 2 images with what is actually running and I have 2 Tabs in Standard Browser of Google and this Tab for this report then a YouTube dedicated browser using split tab.

I’m using the latest stable Firefox package from the official Mozilla repository for Ubuntu, on a system with 32GB of RAM.

I’m also using Microsoft Teams for work calls, in the browser (because Linux) and I notice that Ubuntu has killed the FF process twice last week because it was using too much memory - see attached image. I’ve only had 4 or 5 Teams calls last week so this isn’t a great success rate. It seems that after half an hour or so, FF has hogged so much memory that the OS feels the need to kill it.

If this is a known issue: are there any known workarounds?

If this is not a known issue :Can I help by providing troubleshooting data? How?

Thanks in advance!

Subject: Firefox Sync appears to have erased all bookmarks after setting up a new Windows installation

Hello Mozilla Support,

I believe I have encountered a Firefox Sync issue that resulted in the loss of my entire bookmarks collection.

Here is exactly what happened:

I have been using Firefox Sync for several years without any issues. This was not my first Windows reinstallation. I have restored Firefox through Sync multiple times before. Firefox Sync had always synchronized bookmarks, passwords, history, extensions and open tabs correctly across my Windows PC and Android phone. I had approximately 350 bookmarks, organized into folders. Timeline Yesterday I performed a clean installation of Windows 11. I installed Firefox 152.0.5 (64-bit). I signed into my existing Firefox Account. I did not immediately enable Sync, so nothing was synchronized at that point. Today I enabled Sync and waited for the synchronization to complete. Passwords synchronized successfully. Browsing history synchronized successfully (it took a little longer). Extensions were restored successfully. Bookmarks never appeared.

Immediately after noticing this, I checked Firefox on my Android phone.

At first, one of the bookmark folders still showed that it contained more than 300 items (I saw the item count), but when I opened the folder it was completely empty. After synchronization finished, all bookmarks disappeared from both devices.

Additional information Browsing history is still present. Saved passwords are still present. Extensions are still present. Open tabs synchronization continues to work. Bookmark synchronization is enabled. I am signed into the correct Firefox Account. The second local Firefox profile is empty. The automatic bookmark backup now contains only the current state (7 items), indicating that the original backup has already been overwritten. The current profile contains both places.sqlite and places.sqlite-wal. The only Sync error log is related to a temporary DNS lookup failure (NS_ERROR_UNKNOWN_HOST) and contains no bookmark synchronization errors.

Because history, passwords and extensions synchronized correctly, this does not appear to be an account or authentication problem.

What concerns me most is that I briefly saw the bookmark folder still reporting over 300 items on Android before it became empty. This makes me suspect that something went wrong during bookmark synchronization rather than the bookmarks simply never existing on the server.

Could you please advise:

Is there any server-side recovery or investigation that can be performed for Firefox Sync bookmark data? Are there any diagnostic logs that I can provide? Is this a known issue with Firefox Sync after connecting a newly installed device?

I would greatly appreciate any assistance, as this bookmark collection had been accumulated over many years.

I have a Sync error log available: error-sync-1783454370913.txt

It only contains a DNS error related to tabs synchronization: NS_ERROR_UNKNOWN_HOST

There are no bookmark-related errors in the log.

Thank you.

It all started when I deactivated my account. When I click sign in I'm getting:

HTTP Status 401 –

type Status Report

Description http.401

I've tried clearing cache but I still get the same browser. I've tried a different browser and go to the sign in page to enter my account/pw but as soon as it finishes logging me in I get the same error.

On my personal computer, I have a Profile for work and I was logged in via a Mozilla account using my work email address

I've recently set up a similar thing on my work computer. Signed in using Mozilla account. I have since noticed that on my personal computer it says "Account disconnected."

I'd like to sign in again and sync them so that I always see the same settings, shortcuts, open tabs etc on both computers. But if I sign in right now, will I lose the customizations I've made on the work computer? Which computer will it consider to be the "source" of the newly synced information?

Recently updated from 148 to 152 and it has added these dropdowns to both the address and search bars (see below screenshot) that require additional clicks to get past that I do not want. Ideally I would not have these (or would maybe have the search drop down appear AFTER the search field itself).

Behavior I don't want: searches to appear in address bar. Behavior I don't want: search drop down to appear in address bar at all. I require a clear delineation in my workflow for things I have actually visited (addresses) and things I am planning to visit (searches). Behavior I don't want: search drop down to appear in search bar between address bar and search bar (one tab click should take me from address bar to search bar - now it takes two tab clicks because of this drop down).

Resolutions I have tried: Going to "Settings > Search Engine Suggestions" and completely unclicking "show search suggestions". Going to "about:config" and setting the following fields to false: browser.urlbar.suggest.searches keyword.enabled browser.fixup.alternate.enabled

None of these actually remove the dropdown entirely from either the address bar or search bar.

How do I remove these drop downs aside from downgrading back to 148?

Before facebook using reCAPTCHA I can easily logo in my Facebook and Instagram account, but now I always failed to pass the reCAPTCHA， I report this to Meta no good reply. Only today I did the reCAPTCHA and then got a reminder that facebook cannot detect the reCAPTCHA. I still cannot logo on to my facebook and instagram account due to reCAPTCHA.
