Firefox Community Forum

Firefox is creating very high CPU use with many WebThumbnailExtension Web Connect processes. The processes disappear after shutting down Firefox and other programs that access the internet. Does anyone have an answer on how to prevent this from happening?

MacBook Pro M4 with MacOS Sequoia 15.3.1

I just migrated from an older Mac to a newer one running Mac OS 15 (Sequoia) and none of my bookmarks, autofill info, passwords, cookies and browsing history etc migrated to the new version (135) of firefox that I downloaded. When I check the updates section of 128.7, it says it's up to date, but I know you can run 135 on Sequoia, so that's why I downloaded 135. When I looked at the profile folder in 135, which is existing separately on the Mac from 128.7, I noticed that it was pointed at the folder with release in its name that was inside the profile folder. In 128.7 it's pointed at the other folder with default in the name (the profile folder only seems to contain two folders). How do I get all of my old info to migrate to 135? Or how do I get 135 to point at the proper folder inside of the Profile folder?

Thanks

When printing the same page repeatedly, FF gets increasingly slower and slower each time until it is downright ridiculously slow and takes up to a minute, perhaps more, to get to the print menu. However, if you reload the page, printing is instantaneous (at least for the first or second time). Some history or memory management problems?

FF Version 135.0 (64-bit) on MacBook Pro Sequoia 15.3.1

One test case would be https://api.razzlepuzzles.com/cryptogram. Keep selecting New Game from the pull-down menu on the right and try printing as PDF (or anything else).

Since the latest Sequoia 15.3.1 update and the latest Firefox update, when I click on a link in a page, I often get a message that it "didn't redirect properly" and I have to click on the address bar to make the page finally appear.

/edit: moved thread from Firefox for iOS to Firefox section as you have macOS 15.3.1.

I want to download and install Firefox on my new iMac. As administrator it downloads but the instellation won't run. As a user it downloads and I can move the icon into the application folder. Firefox then opens but it won't run. Everything is frozen. What is going on??

No matter what I do, I cannot find my screenshots. My downloads are set to save on the Desktop (using a Mac, so this is Firefox for iOS).

PNG and JPEG are set to "Save File"

I'd attach a screenshot of my settings, but wouldn't be able to find it if I took it. ;)

I have no idea where screenshots are going. Any ideas?

Thank you

I ahve just bought a new mac, and used the Migration Assistant to transfer all data and systems. It has worked well, except my co0mputer will not allow me to downl;oad any file or program now? Any assistance would be appreciated.

I have no idea how to access the following directions I found trying to address the question of : How to stop videos from following as you scroll down a link huff post …..Firefox 135. Mac 12.7.6

Go to about:config and set media.autoplay.enabled.user-gestures-needed to false to disable all kinds of autoplay.

in Austria I used to sign documents with the mobil phone and TAN-code. The system changed (now ID-Austria) where it is possible to sign documents using fingerprint, eye-scan or a FIDO2-key like Idem-key or YubiKey. It seems that this should be possible for Mac-users using google chrome. I don´t want to install google chrome only to sign documents! Is there a possibility to define a code for using FIDO2 keys with firefox. Keys are already defined in Mac settings but I can not use them to sign. thank you Robert
