firefox not opening since 2022-01 Cumulative Update for Windows 11 for x64-based Systems (KB5008353). I reloaded Firefox. Google Chrome and Microsoft edge work OK. Task manager shows running but stats never change 0% CPU/0.2MB Memory

I look for the smallest zoom possible on the Firefox settings to suit my eyes and I don't find it, there's 67% and 80%. 67 is too small and 80 too big. Unlike other browsers who offer 75% of zoom level, I really want it on Firefox too! If this could come up, it'll look pleasing!

Today, when I had turned on my pc, apparently Firefox had updated (?) my browser and ALL of my bookmarks are gone!?? I had copied my bookmarks from my other pc that had Windows 7 onto my new pc that has Windows 11 several months ago and haven't had any issues (with the bookmarks) - until today. Any help would be greatly appreciated!

Prior to the last update, Firefox was auto resizing my tab background area (I don't know the technical name of this, but its the menu area behind the tabs) to fit more tabs as I opened them, up to a certain number of open tabs. Now the tab background area remains at its full size from the start even if I have only 1 tab open. I prefer the old behavior and I'm not sure what userchrome setting I need to adjust in order to get back to it. The line that is causing the issue is as follows

1. main-window {

 /*--tab-min-height: unset !important; */
 --tab-min-height: 38px;
 --tabs-lines: 8;     /* THIS LINE CAUSES THE PROBLEM */
 --tab_min_width_mlt: 186px;
 --tab_max_width_mlt: 186px;
 --tab-min-height_mlt: 38px;

}

I can reduce it to a lower number but when I do that I am stuck with the tab scrolling behavior that I don't want. Perhaps there is a setting to auto resize the tab area that I'm unaware of. I would appreciate any assistance. Thanks.

Hi guys. I'm on a Lenovo laptop, using Windows 11. Was NOT experiencing this issue (or any other issues) till today. That is, I've been able to download PDFs attached to Yahoo email for years, including recently (till today).

Trying to get Firefox to be DEFAULT instead of MS Edge, I changed some 'Apps associated with File Types', selecting Firefox as default for all file types that seemed appropriate, BUT, this issue then began.

Feeling I went too far, and should go step at a time, I reset All File Type settings back to default (MS recommended settings). Still can't open attached PDFs. I tried an Excel attachment and it opened fine.

Error I get is: "Firefox Can’t Open This Page To protect your security, dl-mail.ymail.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window."

The emails I used to recreate the error, were sending an email to myself, and attaching a PDF.

Other things I tried: I used Firefox with gmail email and the PDF attachment downloaded fine. I used MS Edge with Yahoo email and PDF attachment downloaded fine. Also, btw, CAN view a PDF attachment with Yahoo email. Just now download.

I CAN "open it in a new window" as the error suggests, than print to PDF, but don't want to live the rest of my life doing that.

Thanks in advance for any help that can be offered!!

Access to Google sites (Gmail, Google Search, Google Calendar) with Firefox (v. 100.0, 64-bit) is very irregular. I can sometimes open the pages, but can't, e.g., edit calendar entries. Often when I click a bookmark (in the Bookmarks Bar), or enter the URL for a Google site, nothing happens. Clicking other bookmarks opens the corresponding pages. Only Google sites seem to be affected. Is FF blocking Google?

I cannot say if the last update was the change. I did not have the issue of bookmarked sites and when I log in, no user name or password is provided, as what happens now. Those bookmarks' login information IS still in my Firefox's about:logins, but now they are not being automatically presented. Even after finding the login credentials, logging in & out, returning to sign-in, the credentials just used are not recalled for use again.

That was not always the case and I would like to know if there's a 'setting' now that needs to be 'toggled' so 'Manage Logins' will work as it was did.

98.0.2 (64-bit)

I need to reset my password and I have all my firefox files from "appdata/roaming//monzilla/firefox" but will I be able to restore all my data from it after the reset or will the reset prevent anything? Will it work?

I want to be able to sync my data and know my password for this account.

I am aware that there is a guide for restoring profile data, but I dont know what happens after I reset the password and still try to restore the profile.

Firefox browser opens minimized - about half size. Support article suggests a refresh, tried that and it works for the first time the browser is opened after the refresh and then reverts to the same size.

Another suggestion was to delete the xulstore.json file as it may be corrupt. Done that several times. Each time, that solution works for the first time the browser is opened. Beginning with the second time, the behavior returns.

I have also tried uninstalling and reinstalling Firefox. Same result. Works for the first time the browser is opened.

I have no extensions or plug-ins installed other then what exists from the default browser. I am running the current version of Firefox, Windows 11, fully updated system with plenty of RAM and disk space.

Thanks!

I had been using Firefox browser for awhile, but because of playback performance issue, I have to using another browser just for video playing, especially for 4K video.

Compared to Edge, Firefox seems taking more resources to playback the YouTube video and more heat. When look at the Task Manager, the Video Processing is 0%, and GPU is running significantly more resources on '3D'.

I've always used the "Always ask you where to save files" option when downloading. Recently (beginning of April 2022), files go directly to the Downloads folder. The "Always ask" option is still selected in Settings.

I've tried un-selecting and re-selecting, restarting Firefox, restarting my computer - basically every iteration of 'turn it off and on again' that I can think of.

Hi,

Is there a way to remove the "delete" option when right clicking on items in the download history? It's unfortunately right above 'remove from history' and easy to mis-click. It has no confirmation and permanently deletes the file(s) without sending to the recycle bin which is quite annoying - especially as I'm not sure why you'd want to use this menu to delete something you just downloaded.

Thanks

I'm using freshly-downloaded Firefox version 102.2 on a brand new laptop (Windows 11 Pro version 21H2), and every single extension is showing a "Installation aborted because the add-on appears to be corrupt" message when I try to install. I have tried checking for updates, quitting and reopening firefox, restarting my computer, refreshing firefox, uninstalling and reinstalling firefox, as well as any and all combinations of those. I've scoured these message boards and nothing is working for me. Please help!

Padlet.com will not allow Firefox and I need to be able to access for online studies. Please don't make me use chrome!!!
