Firefox Support Forum

A few days ago links in messages stopped working in Outlook (Microsoft 365) on my Windows 10 Pro 64-bit PC.

Good ol' Microsoft support reset Firefox on the PC and I lost all bookmarks, history and personalized settings. Tried to copy data from Old Firefox Data file into profile on reset Firefox. Didn't work. Uninstalled and reinstalled Firefox and tried to copy data from old profile to new profile. Nada.

Only option now is to try to sync Firefox on my Mac to new install on PC. I'll still lose some bookmarks and history but it will be better than what I have now. I have a Firefox account on both devices but when I log in to Firefox on the Mac I cannot find anything pertaining to sync.

Problem one: how do I navigate to sync in Firefox for Mac. Problem two: when I bought the Mac 6 years ago I tried to sync Firefox on my PC to the new Mac. For some reason Firefox synced the empty new profile on the Mac to the old PC. I lost all bookmarks and history accumulated on the old PC! I do not want to go through that again.

I have never found anything on Mozilla that clearly explains how to control which way the sync works. Must be certain that I'm copying all the bookmarks, history, tabs etc, from the old device to the new on and not vice versa.

Olá. Já faz um tempo, mas meu web wpp não carrega mais nenhuma figurinha. Alguém conseguiu solucionar isso já? Ela fica como um arquivo de midia por baixar. Minha versão do ff é 117.0.1.

obg.

I am running Firefox on Mac OS 13.5.2. Every few videos I watch on Youtube skips a few seconds forward (audio and video). I only started experiencing this problem once updated firefox to 117.0.1 (64-bit).

I've been having this issue for several months now. It seems my Firefox on MacOS (Both Monterey and Ventura Intel) can't load any Google sites (google.com, gmail, google meet, etc) after I put the computer to sleep and wake it up again. Only gets fixed after quitting and relaunching firefox.

I've recreated this issue while in "Troubleshooting Mode" with all my addon's disabled, so it is not related to an addon.

This issue might be also happening after some amount of time idle as well, but I've only been able to recreate it by putting the machine to sleep and waking it up the next day.

Is there a way to fix this? or is there a way to get more debug info to help diagnose?

Hello all,

I'm building a website which uses a `ServiceWorker`. This worker uses `import` to load another JS module. As far as I understand, this should be possible starting Firefox 114 (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import#browser_compatibility). However, it's crashing with an `TypeError: ServiceWorker script at https://localhost:9292/sw.js for scope https://localhost:9292/ threw an exception during script evaluation`. The worker script is loaded as module using `navigator.serviceWorker.register('./sw.js', { type: "module" })`, and working on Safari and Chrome as expected. When I remove the `import`, the worker loads and works. Tested on Firefox 118, 119, 120.

Here is a full sample: https://gist.github.com/fnordfish/9b38b90fba54093ee601887a3bd3e11e

I can't find any related bug in Bugzilla or anywhere else. Which makes me wonder what I am missing.

PS: Non module `importScripts` work.

Hello,

In Firefox on macOS 13 Ventura, links clicked in Google Sheets docs.google.com/spreadsheets/ or in web.telegram.org open in a new window instead of in a new tab :(

If you have any idea why (in Firefox on Windows 11 I don't have this issue :)

Thanks a lot!

The browser window is locked in a fixed position on the desktop. No issues with any other functionality. I don't have this issue when using the original Firefox browser. I searched Google but couldn't find a solution that works for me. Any suggestions?

After updating Firefox a couple weeks ago my VPN will not connect to the internet. My VPN works normally with other browsers but not with Firefox. I have been checking my settings to no avail. The funny thing is that last Sat it started connecting again but come Mon morning I was unable to connect again. I have used this same VPN for years & if I turnoff the VPN Firefox connects immediately... re-enable the VPN I cant connect. I have troubleshooted this issue with my VPN provider & they see no settings issues. I tried disabling my anti-virus but that didn't help. Any thoughts, suggestions?

Hi all, I have been receiving emails frequently from Mozilla about different social issues and requests to join in by clicking on tab, Is this for real?

When I copy the URL of something on the web and save it to a new email, Firefox immediately changes it to a picture. I am creating a list of URLs. I then have to find the (carrot?) click it and eventually get the the URL back to "plain Link". I then have to repeatedly attempt to do a return so I can continue entering below the URL. Why do you make this so hard? How can I stop the change in the first place?

Thank You

Starting today, Sep 1, 2023, any link I click on in Outlook for Mac version 16.76.2 (23082700) starts Firefox 117.0 but will NOT open a tab with the page that the link has sent to it. All it does is start Firefox with a New Tab and nothing else happens. This is happening from emails from all different senders. The only way currently I can get an email link to work is to start Firefox first, then click on the link in the email message which will then open the website. THIS IS VERY ANNOYING! This has never happened since I've been using Outlook for Mac since 2017. I've included a screenshot example of the link in the email that Firefox should be following but doesn't.

I'm having problems with CPU usage (and Mac temperature) after last update in the full screen mode (I use a firefox extention). It may be changed something in last update? When normally in my daily use of firefox I don't have any problems about my pc temperature. Plus it happens that the external links like the Zoom from Firefox to the application or the the "favourites" link pages I added on my dock don't work at the first click, but I have to wait firefox to open, after I click the first time, and then I can open the favourite from my dock

I think you just installed a new version, because a Firefox page popped up, and all the other pages I have open "stopped" working. Maybe because some extension stopped working? Actually a lot of extensions stopped working. I hope when I push the "share data" button down there it'll send you my extensions list.

"Stopped working" means sometimes nothing displays at all; I can't get white-on-black to work; other things I can't remember. This was working a couple of hours ago and suddenly it isn't. So, can you tell me how to back up to a Firefox that works for me?

P.S. I got a this-tab-just-crashed message while reading the troubleshooting info window. Luckily restoring the tab remembered what I'd typed.

URL links in Mac Mail have suddenly stopped opening when the Firefox app is not running. Clicking on a link will open Firefox, but will stay on the homepage and not continue to the clicked URL.

A few weeks ago a small link of the current page started appearing at the bottom of the page when playing videos on every website on every device that has Firefox. Ive seen this link before but it always goes away when I put the video in full screen. A temporary fix is going to another tab and switching back. This makes it go away until I see another video.

I was trying to copy a you tube link and paste it into my hotmail email. Although I could paste the link into a search bar within the hotmail email page it wont let me paste it intoan actual new email I want to send. Ive reinstalled firefox with no success. This problem doesnt occur in chrome or safari. Any ideas? Thanks
