After updating to 91 version almost all my addons stopped working in private mode.

When FF team decided to block all addons for private mode there was a setting in about:config to allow all adons to work in private mode, but it looks like it is removed in 91 (?) or renamed (?).

So, how to enable all addons to work in private mode at once ? I have a lot and clicking each one in its settings will take a lot of time.

I have multiple computers, all Win10, All use Firefox. Recently one computer the HD crashed. I reinstalled Win10, Firefox, and a couple of other MS programs, all used on the other computers. The other computers all updated to 91.0.1, The new install is also 91.0.1. If I try to go to Google.com on the newly installed computer I get: Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.google.com because this website requires a secure connection.

All the other computers search and go to Google just fine. So it is obvious it is something new between Google, Firefox and Win 10, the version of Win10 is 19042.1165 (win10 home) I have searched (using Edge and Bing) for some type of answer, but everything is from 2015/16 and older. Firefox when first installed, before the 91 update on Aug 20th, did work, it was after the Aug 20th update Google (and Bing) stopped with the security issue. I do not care for Edge or Bing, I hope someone can give me some ideas. Thankyou in advance.

Few days ago, I was going to update my browser to 94.0.1 when I decided to check first "what's new".

To my shock and horror, I read: "On Windows, there will now be fewer interruptions because Firefox won’t prompt you for updates. Instead, a background agent will download and install updates even if Firefox is closed".

Seriously?... this is not an "improvement". This is just a nice way to say "we are taking over the control of Firefox updates and remove all user choice in this regard".

What is the rationale for this change?

I don't allow any programs to download and install to my PC without my knowledge and permission (including Windows Updates and even Wordpress and plugin updates on my website). I decide if and when anything gets updated to avoid crashes and other computer issues, as well as to prevent installation of something I simply don't want. This includes browser updates.

Secondly, I finally managed to reduce the space between bookmark lines in menus with a workaround in the about: settings after months of struggling with the settings created for iphone users which are unworkable on my PC (the only device I ever use the browser on).

Could someone in the know confirm please that (1) this workaround will continue to work in 94.0.1 (as the release notes are suspiciously silent on this) and (2) that this option will be permanently reinstated in the browser settings with the next update.

I am not updating my browser until I get more information about the issues I have raised, using Chrome in the meantime and...indefinitely.

thanks

Hello,

after installing 98.01 recently a tab was opened that informed about a feature for Firefox installations on smartphones: the site said that it is possible to continue my work where I stopped before, including open tabs, bookmarks etc.

I don't have a smartphone - I only use firefox on my notebook. Since I'm considering to buy a new notebook in the upcoming weeks I ask myself how it is possible to migrate my current firefox installastion to a new notebook. Especially I'd like to have all my open tabs, bookmarks and cookies back after having installed firefox on the new notebook.

How can I do this? GreetZ and thanks a lot in advance!

Starting today, I went to download a .pdf file to open automatically with Adobe Acrobat as I usually do. However, this time I got a pop-up from Microsoft Word stating, "Word will now convert your PDF to an editable Word document. This may take a while. The resulting Word document will be optimized to allow you to edit the text, so it might not look exactly like the original PDF, especially if the original file contained lots of graphics."

I went to Settings - General - Applications, went down Contents list to Portable Document Format (PDF), and tried the various settings under the Action column, to include "Save File," "Always Ask," "Use Acrobat Adobe 2020." None of these worked or made any difference. I open numerous .pdf files every day and I need to be able to just click on them in the website and have them open in my Adobe Acrobat program - as they have up until today. What do I have to do to fix this? I am using Version 102.0.1 (64-bit).

I use both firefox and firefox dev edition. Deleted the dev edition and reinstalled the latest one, now i'm getting the error below on attachment. I did not just uninstall the dev edition but i manually cleaned the directorys: C:\Program Files\Mozilla Firefox Dev Edition C:\Users\User\AppData\Local\Mozilla\Firefox\Profiles C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles

Firefox still works but the new dev edition after fresh install doesn't

I just installed Firefox on a new Windows 11 desktop computer. I ported my profiles over and it appears everything came over EXCEPT: - Themes aren't working. I've tried switching them and they still don't display. The menu bar is black w/white letters; the toolbar is gray with white icons/letters. - My extension icons are there...sort of. If I hover over them I can see the tool tip but the icon doesn't appear on the toolbar which is light gray in color. I can live without the themes if I have to. Not so much the invisible extension icons. Any suggestions as to how I can get them to appear as they do on my Windows 10 desktop? Screen cap below. Cursor is hovered over the Undo Close Tab extension icon but where's the icon? Any suggestions as to how to troubleshoot this will be appreciated!!

I recently upgraded from 108.0.2 (64-bit) to 109.01 but it slowed my PC down to the point of uselessness. Nothing else changed application or OS-wise. PC, OS and all Apps are current & up to date. Defrag, Cache Clear a& all similar utilities run on scheduled basis prior to upgrade and everything A-OK.

Is this a Known Issue? If so, is there a fix coming

Firefox is making itself a "pain..." again. It is now unhappy I am using an OLD PROFILE and wants me to use/go to a new one.

Your advice? Of course I hesitate as going to rel 87.0 got me into this trouble in the first place by losing EVERYTHING and forcing me to create a new profile, while "hiding" everything and started me from scratch. So now again, "I hesitate". I am almost 84 yo and I cant keep trying to recover FIREFOX bookmarks, add-ons...history.. keeps losing with every release.

Your advice? TRY to get at least, the bookmarks I recovered to a "new" profile or ignore FIREFOX and keep using my old working profile? Anyone find a way to "recover" lost ONETAB URL's?

Hello, my Firefox won't load at all. I've tried to reinstall but it still didn't work. I've also tried to access the profile manager but it wouldn't load either. Any thoughts?

System Elementary OS 5.1 (Ubuntu 18.04) Nvidia 465 driver

Tried with Firefox from Ubuntu repos and Flathub

Problem Since the update, I have this rectangle (see picture) on all websites, even the settings. This makes Firefox unusable.

What I already tried

1. Numbered list item Started Firefox in Troubleshoot-Mode, where everything works normal. Nice.
2. Numbered list item EDIT: I also tried the "Refresh Firefox" option, with no success
3. Numbered list item I purged the Firefox install and removed all configs, addons etc. on disk (removed /usr/lib/mozilla, ~/.mozilla, /etc/firefox). Sadly, the Problem is still there.

So it works in Troubleshoot-Mode with my personalized Firefox version as well as a clean install, but never outside of Troubleshoot-Mode.

Question As a clean Firefox (see above) seems to work as intended, how do I reproduce this behavior outside of Troubleshoot-Mode? What changes between Troubleshoot-Mode and regular mode? Any advice?

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.

When Firefox updated to version 90 then 91, the Tools/Settings selection doesn't work. I can select "Settings" but nothing happens and I can't change any settings.

I've reinstalled several times to no avail and have had to switch to Brave for the last couple of weeks.

How do I fix this?

Thanks!

P.S. I find I can't access the internet at all now.

Hello,

since yesterday after closing FF to restart, I encountered a problem. Everytime, when I try to open FF, it says that the profile isn´t available or not accessible.

I tried already to rename in /library/Application Support/Firefox, Profiles.ini -> Profiles.iniOLD and the folder Profiles -> ProfilesOLD.

As well I tried to call the Profile Manager from terminal using the below commands, since FF isn´t open. /Applications/Firefox.app/Contents/MacOS/firefox-bin -P /Applications/Firefox.app/Contents/MacOS/firefox -ProfileManager

No matter, whether I rename the profile.ini or try to call the profile manager. Each time I get the same warning, that the profile isn´t available.

Since I tried every possible solution, which I could find on the help pages, I hope to find help from the community.

best regards Corey

I used to run Firefox 88.0.1 (64 bit) on a Windows 7 PC. With lots of help from this forum I wrote a userchrome.css file to make several changes to the appearance.

On a new Windows 10 machine I installed the same version of Firefox (since I don't care for the latest one). I added my old profle to the new installation and selected it as the default.

Unfortunately, when I opened the program I was prompted to create a new profile; there didn't seem to be any way around this. So I let it happen and tried simply copying my old chrome folder into it - I thought at least I could make the visual changes even if I couldn't import my bookmarks and so on.

But this didn't work either: when I run the program, none of the expected changes are there.

Presumably I've done something wrong, but what, exactly? I'd be grateful for any thoughts. Ideally, I'd like to use the whole of the old Win7 profile but if that's not possible at least changing the appearance would be pleasant.

Many thanks.

I just tried to install the latest version of Firefox, but couldn't. Not because the link did not work, but because of 2 different warnings not to I got. 1 was from Windows and the other from Avast. I'm concerned about the warnings. Can anyone help me with this?

I downloaded the updated version of Firefox and replaced the old version, but my system won't accept the newer version. How do I reinstall the older version for my Mac.
