Firefox Community Forum

Since I upgraded from FF128-esr to FF140-esr I always get the "Firefox is being updated by another instance" This is really driving me crazy, as I checked / did / .... everything (and even more) I found on the internet related to that.

Nothing helps !

Creating and using a new default profile didn't help

Finally I ended up uninstalling FF completely (making sure no -zero- leftovers remained in ProgramFiles, AppData a.s.o.), and reinstalled FF140.7.0-esr freshly. After installation I started FF immediately with the created default profile (only existing one) --> SAME THING : "Firefox is being updated by another instance"

And this is really a FF140 thing, when I go back to FF128, on the same computer, same profiles, ...., the problem is gone.

I would like to know in detail what checks are really done by FF to decide to give that "Firefox is being updated by another instance"

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?

All of my history except of today's has disappeared. I did not erase my history, and really need it back. I did try to remove a couple of sites from my Most Visited, as Firefox was saving all sorts of sites I don't really visit often. In addition, I am being asked to sign in with my password at every site I go to where as before I was automatically allowed to enter, as all my passwords are saved. What happened - and how can I get back to normal?

Contributor note: bookmarks are also missing (/questions/1578816).

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

Hi, I had to reinstall my windows where I thought my Firefox would sync up upon reinstallation. However, nothing would sync up and the best I could do myself was to import pretty out-of-date Chrome data. When I to my firefox account and scroll to connected services I see my last PC name with its firefox login. Is there any way to recover that data and import to my current device? I read you kept sync data as encrypted data on your Mozilla servers, so I hope that's a viable solution.

I have been told to disable my ad-blocker by some commercial web sites and I understand that. But I am also not seeing charts and other non-ad items on web sites such as this one: https://www.medscape.com/viewarticle/alcohols-health-myth-over-how-tell-patients-2026a1000map?ecd=wnl_tp10_daily_260703_MSCPEDIT_etid8475291&uac=146695DK&impID=8475291. I don't want to change my default browser but this is a recent development that seems to be impairing my viewing of pertinent items placed on legitimate web sites. Could you please tell me how to adjust my browser settings to stop this from happening? Thank you! Best regards, Bill Strike

See the subject. I've been seeing delays in launching for several months. I've run several windows defender malware checks (full and the one where it runs outside of anything brought up). I've reset firefox. I did all this also because I was seeing random ads from a news site from what they were trying to get me to do was install macafee (but it's malware). While I'm not seeing those ads now and I'm suspicious they can from the news site vs. my browser, I'm very aware of anything trying to capture screen scrapes. I'm even considering changing all my passwords as I'm not sure if anything was captured. This morning, firefox upon launch took a long time. Then it said installing updates. My desktop flashed and firefox launched. I have not installed anything or any addons, extensions, etc. So either this was firefox doing an update it needed or it's something else. I'm on windows 10.

I wish to add an exception to an address which I host locally. I've explored many options which didn't work such as: Adding HTTPS-Only Exception Disabling certain security features

Since the last update, I have noticed that some websites/webpages are no longer available, one of which is Lincoln Financial. I can only get so far and I get errors. It is NOT on Lincoln Financial's end, as the site/pages open perfect in Chrome and Safari. This is something new with the security/privacy in Firefox, I am assuming. I need to be able to access this sight, as it is my Long Term Disability site/page, which I need to have communications with.

I think this is going to have to be dealt with on more than a simple help thread. this is going to have to be dealt with with tech support.

By Firefoxwss working great the last time I used it it is the primary search engine for my iPhone 17 as well as my Mac however, when I loaded it today it the screen just said blank. All of my bookmarks are on Firefox. How do I get this fixed quickly? I am, right now being edited. I’m sitting here looking like a fool because I chose to use Firefox rather than Safari or Google. First question they ask me why are you using Firefox. And then, of course, Firefox /x I/ dies all of my bookmarks are on Firefox. Firefox will not open! I have used Firefox for the last nine years. Never had a problem until today when I needed it not to have a problem.

This is Firefox on a brandnew Fedora installation. Using Jupyter notebooks on Google Colab, I experience delays when typing into input fields. It's not quite a deal-breaker, but annoyingly sluggish. On a Chromium-based browser, Vivaldi, I don't notice this problem.

My hope is there is a certain overlap of the demographics using Colab, Firefox and Fedora. I wonder if there is a known problem in this area? Is there a configuration settings you can suggest?

Thanks in advance!

Bernd.

Had an IMPORTANT list of websites that were listed just below the top search bar. They have disappeared, and I need them back where are they and how do I place them back where I had them. Signed, Technically challenger senior that requires step by step instructions, basic skills please :)

When watching videos on youtube, I hold down the space bar to make it go at 2x speed, this makes the video and the audio de sync the more I hold the space bar, It's been happening for quite some time and I can't seem to find an answer as of why this happens or how to fix it.

Somehow NordVPN caused my Firefox bookmarks on my macbook to be deleted (Nord has caused more problems than I've had in years). Many of the bookmarks are still on FF on my ipad. I've setup sync on both devices (at least I think so), but when I hit the sync button on my mac, the ipad's bookmarks don't appear on my macbook. On my ipad mozilla account 'everything I'm using and signed into' shows the macbook was active 7 minutes ago, and the 'sign out' box is available, so I must be signed in. Firefox on my iphone is the same. Any suggestions. It's getting to the point where it would be easier to setup new bookmarks.
