Why, with not very many active open windows, and just after opening, is FF using 175% of my CPU, not counting all the separate listings in my Activity Monitor. Plus it's using nearly all 16 GBs of my RAM. With every new update, I pray it will mean the browser will just work, and not use up all my computer's resources, but it just never does. Pretty soon, more & more of us will just give up on this browser, which used to work better, years ago, and has only gone downhill since.

I tried to close it one by one by "end task" option but still, every time I open Firefox again these tabs or whatever they are are back and using memory more than any browser

After upgrading Firefox from 102 to 103, LastPass Federated Login extension hangs (blank white screen) after Okta login completes. Firefox 102, works fine. Unfortunately, I cannot stop the automatic upgrade for Firefox. LastPass is critical to my work and I've uninstalled it as a result. I've contributed to both Firefox and Thunderbird as I believe they are the best at what they do.

Please let me know when this will be fixed, or how to disable automatic upgrades.

I notice that this problem was reported way back in 2021, but rather than being resolved it was archived ! Well I suppose that's one way of whittling down problems logged on your stack of problems.

I am using 103.0.1 on a Mac Mini running macOS Mojave.

Like you, I'm being lazy and rather than typing a complete explanation of my own, I've simple cut and pasted the description from your previous complainant.

This action is prevalent when I close the right-most tab and whammo, full screen which then causes me to have to mess around to get the window back to the size I WANT IT, and not full screen as your software would seem to want it !

        • Previous complaint ****

Using latest version of Firefox for Mac (although this problem happened with some previous versions as well).

When I have more than one tab open, and I click the X at the corner of a tab to close it, my Firefox window suddenly jumps to full screen. I have to drag the browser window from the edge to get it back to my original size. This behavior happens at other odd times as well, and the suddenly jumping to full screen gets really annoying. Any suggestions as to how I can fix this problem?

        • End of previous complaint ****

I suppose that one potential fix would be to ditch Firefox and revert to Safari, what do you reckon ? I wonder if Safari exhibits this extremely PERVERSE way of working ?

Best regards

I am sorry to invoke other browsers here, but I have switched from Chrome and found one feature to be completely intuitive there and impossible in FireFox. I have multiple profiles and want to open external links in the most recently active window. With Chrome, this was as simple as activating the window to open an external link in, then running the external link normally. In Chrome the link would open in any window that was recently active, including private windows. In FireFox it will only open in the first opened window of the first opened profile. I have not found an intuitive way of handling this in FireFox. Is there a setting or trick to it that doesn't involve rewriting URLs?

Greetings. For the past several weeks I have been unable to log in to spectrum.net to pay a bill. Currently running Firefox 103.0.1 (64-bit) for Windows on Win 10 Pro 21H2. I cleared cache and deleted cookies for spectrum.net, and performed a password reset with spectrum.net. Each login fails with: "We’re sorry, we’re unable to sign you in. Please try again later. IDID-3210."

Contacted Spectrum support, agent reset the password, and was able to log in using Chrome. I then ran Chrome and successfully logged in with the new password, and successfully changed the password and logged in again via Chrome.

Login still fails in Firefox.

Hello! I switched to firefox a few months ago. It worked okay with my rollo printer (printing mailing labels) for awhile, but it's suddenly not working right. Labels print off at strange sizes and with garbled images and text. It works fine if I print from chrome or from my desktop; just not from the firefox browser. I'm wondering if there was an update recently that broke it and I'm really hoping it can be fixed, because I'd like to keep using this but I run a business and it's far too irritating to have to keep switching to chrome to print stuff... I also am positive this is a firefox issue because my partner is suddenly experiencing the same issue after switching from chrome.

Why is Firefox limiting my file name to 3-5 characters instead of the full name as the original document? My Gmail Workspace account is a business account so I need to retain proper naming conventions and original names for files, but Firefox seems to be shortening the file names, and I'm having to completely rename. I can't find any information on how to override this if it's a setting or if anyone else is having the same problem.

I am running Firefox 103.0.1 on macOS Monterey 12.4.

Thanks in advance.

Good morning:

I updated FF 91 ESR to 102 ESR and I'm not liking the Print interface. The main problem is that the printer properties are not available. The printers default is to print from tray 2, but sometimes I want to print from tray 1.

If it can be changed then I prefer code that I add to User.js "user_pref("print.tab_modal.enabled", false); " is being ignored.

thanks Norbert

For maybe a month or two I have been seeing some strange behavior with Firefox closing after I close a downloaded file. Here are some examples.

Lets say I am checking my email (yahoo) and receive a video file attachment. I launch the attachment which is set ot download and automatically open my player, which is VLC. VLC launches and plays as normal. When I finish, I close VLC and find that a few seconds later my Firefox window or tab also closes.

This is not just with video files and not just from email. Same for doc files or pdf or jpg files. If it downloads and then I open it through Firefox, that tab closes once I close the third-party program.

I also tried turning off the auto-launch and just download the files, but if I start them form the downloads display in Firefox the same issue occurs. If I start explorer and browse to downloads and just launch it from there then there are no such issues.

I did notice that it only closes one tab, so if I have a dummy second tab, when the tab is closed I can use Ctrl+Shift+T to restore the previous window and continue, but it has gotten tedious to do that every time I download a file.

I did check that neither Chrome of Edge do not have such behavior.

System details. Firefox 103, Windows 10 21H2. No known major updates or changes have been made to the system to cause this change. The only extension I have is Ublock Origin, and I have tried disabling it but it did not help the problem.

The scrollbar in Firefox 103 is too thin which impacts accessibility.

I tried various options in about:config and nothing worked.

I then changed the Windows 11 scrollbar settings directly in regedit and Windows showed the changes. Even Chrome changed the size of its scrollbar but Firefox refused.

How do I change the scrollbar width in Firefox 103? It's difficult for me to click on it as I get older.
