Firefox Support Forum

This morning I got a message to install Firefox V89.0. Visually this was a disaster for me. The bookmark list is now vertically spaced much wider so I have to scroll up and down the list rather than point and click. The tabs at the top of the screen which used to be easy to differentiate now blur into one. Worse still there was no easy way to back out this upgrade while I found a workaround to correct these problems? I have spent a couple of hours now, researching, exporting bookmarks, uninstalling Firefox, restarting computer, re-installing the old version (v88), Importing bookmarks, finding the icons that were on the bookmarks have disappeared, kicking the cat (metaphorically speaking), reinstalling the new tab add-in, making sue auto update is OFF. Basically a huge pain.

Is there no easy way to rollback updates? especially when the user interface changes are so invasive?

After an automatic update Firefox had a terrible surprise for me. A beyond ugly user interface. And NO WAY to fix this with a simple toggle switch back to classic mode. There are theme's available, but still it looks unusable to me. This kind of updates should be beyond Mozilla, maybe don't hire former Apple employees, the esthetics don't have to be " slick and modern"

So after a long fight with almost losing my plugins, saved tabs (100+) etc.. I downgraded successfully to 88.

Step 1 (Secure your profile) Open menu, Click Help, Click "More Troubleshooting Information" Go to the line which says, "Profile Folder" Hit open folder

Pay extra attention during these steps: Now you are browsing in your active profile. If you did this after upgrading to 89 version. Make a back-up copy of this whole folder!! Rename it back up.

Open the file "Compatibility.ini" with a text editor, and empty it. Save and close.

Download and install the previous version of Firefox, After installing don't forget to disable automatic updates.

If the profile isn't loaded, browse to "about:profiles" and find and select your profile to get al your plugins, tabs, favs, etc. back.

Its a terrible shame i need to write this down for people to avoid the frustration of a terrible update

I'm hoping to bring my Chrome favorites over to Firefox and use the easily. When I was using Chrome there was a problem with duplicate favorites and I think I have 3 sets of duplicate favorites. I asked about this online and I was told that by using switching to Firefox and then importing my favorites from Chrome would eliminate the duplicates. When I first brought them over they were put in my bookmark toolbar. I think I did this but what a mess. Is it better to take my Chrome bookmarks into a separate file where I can pick and choose the duplicate bookmarks and then bring them over to Firefox? Of course I don't know how you do that and I'm just not computer savvy. Thank you for your time and any help or advice you can give me. I'm just frustrated so thanks for your help.

Sincerely, Rob

Windows 10 changed my default browser to Chrome and will no longer let me choose Firefox as my default browser in Settings. Has this happened to others, and is there a solution?

Dear Firefox community, I do not know why you are not solving your browser-short time memory loss problem! When I download a video / file, the internet is disconnected in the middle, and it takes a while to connect, then the download starts again from 0%! It wastes both my time and the internet. If the power connection is disconnected while downloading again - I don't get any backup of that file when I connect to the internet after the power connection is restored ...! However, other browsers have this advantage. I like Firefox a lot, but this short time memory loss system bothers me a lot. I hope to fix this issue in the next update.

Just run firefox update. Wish I hadn't. The tabs along the top are so hard to read unless they are the current one. Can I cancel this update and go back to old version? If I can't get this corrected I'll have to give up on Firefox and find something else.

I've managed multiple profiles, and used the profile manager for years.

Usually, when I want to update/replace a session from one profile to another, these are the files I transfer.

When I launch the profile, it should open to the same tab as in the previous profile, and the tab count should be the same. That is, until today.

No matter what I try with the new profile, the same old session keeps coming up.

I work with a site from where I can download content only from a pop up window, but when I do click on the download it does not show progress. However, in my regular window(non pop up) when I download any content I see the download progress. Is there a way to enable download progress icon in the pop up window toolbar?

What setting will stop the constant notice "Download the latest version of Firefox." I don't want 20 notices per day. It's like having a child in the backseat "are we there yet?" "are we there yet?" "are we there yet?" How many times do I have to click the "Dismiss" button before this stupid software understands that I do not want updates? I've noticed that this is a common complaint. Stop the bullying by making people choose automatic updates. Many times things get messed up on my computer with updates and it is not worth the aggravation. Candace M.

Installation in German language under W10 Home 64bit. VCRUNTIME140_1.dll not found, installation interrupted. Firefox seems to be installed, but totally unresponsive (no files, no websites, not even parameters). Any known measures? Thanks!

Bonjour, Suite à la dernière mise à jour de Firefox, j'ai sans cesse le message d'erreur VCRUNTIME140_1.dll introuvable. Conseil de réinstallation de l'application etc. J'ai beau faire une désinstallation complète et un nettoyage puis une réinstallation, rien n'y fait. J'ai toujours le même message depuis plusieurs jours. Et c'est énervant ! Je suis obligé de naviguer sur Edge et je n'aime pas du tout. Merci de m'aider. Bonne journée. Philippe

I downloaded Firefox 89.0.1 via Microsoft Edge from the regular mozilla.org site.

I was redirected to this site after the download started: https://cdn.stubdownloader.services.mozilla.com/builds/firefox-stub/de/win/[...]/Firefox%20Installer.exe

I was confused when I saw, that the sha256 checksum mismatched with the one in the repository. Also after multiply downloads from the mentioned site, I recognized all installation files had different checksums.

Is this a bug or a malicious firefox download? Or smth else?

Thanks in advance.

Hi...for 3 days I've been unable to download anything from Hulu, Amazon Prime, Kanopy or Hoopla. Instead there's the message repeatedly about Firefox installing components to make it possible to download---anything. "Please try again later." I am not happy.

Hi,

I got a McAfee report on the first machine that I tried to deploy this file.

Firefox Setup 89.0.1.exe contains the GenericRXAA-AA!92712AE6AC5F Trojan. Undetermined clean error, OAS denied access and continued. Detected using Scan engine version 6200.9189 DAT version 10008.0000.

I scanned the file with on VirusTotal and verify the hash. It doesn't bring up anything.

Does someone know anything about this?

Thanks.

Under an "about:profiles" profile, selecting the "Open Directory" button opens my Linux "Document Viewer" with an "Unable…" warning; expected because that's not what Document Viewer is for.

This could be exactly as predicted in my preferences, but I didn't find any means to redirect that button action at a different helper. I expected it to routinely use my default file manager application and this was a surprise. All I could find searching for the issue focuses on URLs which isn't my problem; I can enter (or copy/paste) the displayed path beside that button okay as "file:///…," so I can call that the workaround.

How is this button action set? Is it a simple thing buried somewhere in the settings?

My old computer crashed but I have access to the entire hard drive on my new laptop. I'd like to restore Firefox on the new laptop exactly as it was on the old laptop (bookmarks, tabs, etc.). All of the help articles talk about restoring from a backup, but I never made a backup since I obviously didn't know my computer was going to crash. Which files do I need to access from old hard drive and move to my new hard drive so that everything looks the same as before? Any help would be appreciated.

I am using Linux Mint 6.0.3.1 , and my Mozilla Firefox version is 77.0.1 . My Firefox will not update, neither automatically nor when prompted. When I go to all the pages for downloading and installing the newest Firefox, I am always able to download a package, which appears as a folder labeled " firefox-89.0.2.tar.bz2 " but then I cannot install it, it just appears as a folder full of files that will not run. I have tried following the command lines in the terminal that these pages claim will make the new version run, but I always just get a response like "no such command" or "no file exists." Shouldn't there be some relatively simple and reliable path to just get firefox 89 onto my computer?

I just upgraded to Firefox 89.0.2 from a very old version of Firefox and noticed that the Open Tabs drop-down is missing. This is the symbol that appeared on the far right end of the open tabs that allowed me to see all of the open tabs in a drop down list with the entire tab name showing. How can I get this back?
