Firefox Community Forum

I regularly use a website which intercepts command-option-up and command-option-down for its own navigation. This is a central part of my workflow with this website, and without it it becomes completely unusable.

After updating to Firefox 140.0.4, these shortcuts are now used by the browser to switch tabs. I have not found any way to configure this. Am I missing some obscure way to do this or is this just impossible?

I imagine this change was made to support vertical tabs, but I'm not using those, so the command-option-left and command-option-right shortcuts make more sense for my horizontal setup. (I don't use those shortcuts either, though- I use ctrl-tab and ctrl-shift-tab!)

Recently all my 100 plus Bookmarks all went to Grey Globes. Never had this issue in years with Firefox. I am working on Mac OS desktop version Ventura 13.7.5 and Firefox 140.0.4. How do I get all my bookmarks to come back to normal? I tried hard refresh and cleared my cache.

After update to 140.0.2, clicking on Firefox icon in the dock does nothing. The title bar says Firefox is active, but nothing shows on my screen. What changed? Did you reset something in my preferences?

Hi! I recently lost my old laptop and I'm trying to setup my new laptop without a backup. I was logged into my mozilla account on my old browser before I lost it, but I'm not seeing any of my old tabs, bookmarks, and extensions from my old browser syncing to my new browser. Is there anything I can do to retrieve this data without having access to my old laptop? Thank to anyone who can help!

Firefox crashed and I cannot recover my tabs from history. I click on restore all tabs and it does nothing. The tabs I was hoping to recover do not even appear in my history either.

Hi,

Yesterday I opened Firefox and found that it had completed a factory reset (without asking me) and I have lost all of my data and settings, particularly from plugins (Simple Tab Groups for example). I have a folder called Old Firefox Data on my desktop, and I have copied the files into the profiles folder from about:support, but I have still lost all my settings.

This is extremely frustrating and will take a lot of time to get everything back to how it was. Please let me know how to restore to my old state.

Hey, Please my metamask is no longer opening over the past few days, its just showing the loading icon in an infinite looping continues and never stops and never opens. Attached the pics for the infinite loop below:

I can't remember my Firefox log in ID and password and I need to sign in. At the sign in window for Firefox there is not option to click on "forgot password" or "forgot User ID" . Does any one know how to recover that information?

all bookmarks have disappeared along with my passwords. how do I get them back? previous answers haven't helped. before that, I would have trouble playing video and audio together, if I turned the audio off the video would work then when I turned the audio back on the video stopped. I am about ready to delete Firefox and use another browser.

hello,

i attempted to update my Firefox this morning and the app froze and refused to reopen after multiple attempts. i decided to throw the app away and re-download firefox on my desktop, but now have no access to my bookmarks, open tabs (history) and passwords. please assist!

I want to set firefox to use noai.duckduckgo as my default search engine so I can continue to type queries in the address bar. How can i change the settings to include noai.ddg as a default option?
