Firefox is giving me an error on https://stemgateway.nasa.gov but the site is perfectly accessible using MS Edge and using Firefox on another computer. I uninstalled and reinstalled Firefox, changed the proxy settings to not use a proxy, tested a VPN, and changed DNS servers. Below is a picture of the error and of the certificate which seems to be present in Firefox already.

After the Dec 10 update to 133.0.3 (aarch64) on my MacBook Air macOS 15.1.1, all of the menu keystroke options are greyed out. Also, in Settings, Firefox is selected as the default browser, but the option is greyed out so that it is not possible to change. I've disabled all add-ons except my password program, tried troubleshooting mode, and restarted.

i need to copy and paste text that's also a link, but firefox isn't letting me highlight it, I can do it in chrome, brave, & opera, it's not a mouse problem either, if I just right click on the page and select "highlight all" FF wont highlight it, is there a setting for this or a extension I can download? (in the picture the the rad text is also a link, I need to copy the number portion)

Hello, I recently found Ecosia search to be force-installed in firefox, and after much digging I found this to be because of a new collab between them and mozilla. However, I HATE when things gets forced upon you, its the only reason I have stuck with firefox this long.

I cant seem to find a way to remove this search option from my providers list, please instruct me on how to do this, cause if I cant, I will unfortunately have to drop firefox as my browser.

//Kind regards

I got a new Windows 11 Dell XPS laptop computer and installed the latest Firefox (v133) on it. On my old computer, it was supposedly syncing/saving the bookmarks in the Mozilla cloud or somewhere. However when I try "Import" on the bookmarks panel, it only offers to import Microsoft Edge bookmarks. When I follow the help docs on this forum, it says to use the hamburger menu to go to bookmarks and then to "Manage Bookmarks" which took me a while to find since it's at the very far bottom of the Bookmarks window, not near the three menu items at the top. Anyway, it brings up a window with more bookmark items but they all seem to deal with my current computer and installation of Firefox, which has only a very few default bookmarks. I do not see anything related to bookmarks synced with the cloud. I am logged into Mozilla on the new computer. I do not have an HTML backup file available, since I thought that the bookmarks would be backed up to the cloud and I could always get them there. Two questions:

1. 1: Is it possible to get my old bookmarks from the cloud?

1. 2: Is the bookmarks have not been exported to an HTML file, is it somehow able to get them from someplace on the C drive of my old computer? I think it should be possible since the bookmarks must be saved somewhere otherwise, how would it know what the bookmarks are for someone who never exported them to an HTML file? My old computer won't boot due to a power surge but I am able to connect it's hard drive to my new computer and see files on it.

Thanks, Mark

I've noticed that whenever I press ⌥⇧Space (option-shift-spacebar) in Firefox Developer Edition, it causes the page to refresh.

This behaviour seems to be consistent across devices.

Is there a way to change/disable this behaviour? It is very inconvenient, as it often causes me to accidentally trigger a page refresh when I type an em dash (`—`) in a text input (opt-shift-dash, and then type a space character after it, I'm very likely to hit opt-shift-space by mistake 🙈).

Can you tell me the key(s) to open the AI Chatbot sidebar under Firefox Labs? (or implement one if you haven't) every time i hit the X to close it (as it takes up a lot of space) there is no easy way (that i can find) to reopen it without clicking through a bunch of stuff. Thanks!
