I have followed the steps in the "Prevent Firefox from starting automatically" article: https://support.mozilla.org/en-US/kb/firefox-starts-automatically-when-i-restart-window

But Firefox keeps starting automatically when I restart my computer. Attached is an image of how the settings are now.

What should I do? This is a bit annoying. I don't use Firefox as my main browser but I work as a customer success manager for an online platform and always need to do some tests on Firefox, but I don't want it to start automatically when I turn on my computer.

I'll for instructions.

Thank you

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.

I have the same issue that was reported here: https://support.mozilla.org/en-US/questions/1358340 and here: https://support.mozilla.org/en-US/questions/1409149

After a Firefox restart for a version upgrade, there are 8 windows listed in the Windows menu, but only 4 are visible. Trying to select one of the invisible windows from the window menu, or cycling through open windows with cmd-` displays nothing. I tried checking other desktops to see if the windows had landed there, but they're not. The missing windows don't show up in Mission Control.

I also tried exiting FIrefox, deleting the xulstore.json file, and restarting. This had no effect.

I'm on a 2021 M1 Max MacBook Pro Firefox 117.0.1 Mac OS 13.5.2 (22G91)

Any ideas? This is a weird one.

Thanks!

Although I have disabled all relevant "sync" settings in Firefox, the browser is still syncing tabs across my MacBookAir and my iMac.

To make matters worse, tabs in Chrome and Safari sync to Firefox tabs across devices as well. The sync occurs in both directions.

I am not logged into Chrome or my gmail account.

Specs: MacBookAir: early 2015/ OS v. 12.7 (Monterey) iMac: Retina 4K, 21.5-inch, 2017 / OS 12.6.8 (Monterey)

Things I've tried:

• Turning off syncing in Firefox on both devices.
• Signing out of Firefox from both devices.
• Disabling "sync open tabs" via Firefox preferences
• Renaming devices from within Firefox Sync. (The name always reverts to the previous one.)
• Reinstalling Firefox
• Deleting cache from both Firefox and Chrome.
• Restarting

Images are from toolbar on iMac when Firefox is open on both computers. Any help would be most appreciated! Thanks!

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?

I have Mac Pro 2018 and having a problem with Thin Lines on left side of the browser (Firefox Mac) i can't find anyone on line with same problem explaining how they resolved the issue!

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).

Today, randomly, duck duck go no longer works natively with Firefox. If I set DDG as my default search, and try to search using the search bar or use one of the shortcuts like "@ddg" I get an error "Firefox has detected that the server is redirecting the request for this address in a way that will never complete." I have tried closing, clearing cache, clearing history, and nothing seems to reset it. I can still go through Google, search for duck duck go, and use it that way, but it seems that the native search is now broken.

Autoplay media blocking does not work. I've tried to block autoplay on sites settings and also done this about:config fix without results.

   media.autoplay.default = 5 [0:allow;1:blockAudible;2:Prompt;5:blockAll]
   media.autoplay.blocking_policy = 2
   media.autoplay.allow-extension-background-pages = false
   media.autoplay.block-event.enabled = true '

Videos still start playing in some websites. I've noticed that when reloading the page, then autoplay blocking works.

Example: https://www.iltalehti.fi/formulat/a/35242327-7699-45a2-a1b5-75ff330a9d13 When i go to page first time, it shows on the left of address bar, that autoplay function is not even enabled (no autoplay block icon). When i reload/refresh the page, then it shows that autoplay is disabled and autoplay block is working properly (icon appears).

So it's only issue when visiting the page first time, if page is refreshed, no issues.

Using Firefox 17.0.1 on MacOS Ventura 13.6 on my 2017 iMac I am unable to connect to the internet while using Private Internet Access (PIA) VPN. All was working normally until I installed MacOS Ventura 13.6 yesterday. The VPN works normally when using Chrome or Safari. I have tried changing my network proxy setting without any luck. The default setting is "Use System Settings", using No Proxy or Auto Detect Proxy doesn't help. I don't see a switch for Enable DNS over HTTPS. All works fine when the VPN is disabled. I tried deleting the VPN a couple of times then reinstalling but that didn't help.

What am I missing here? I have used this VPN for years without any issues & it worked on Firefox until I installed MacOS 13.6...... using 13.5 I had no problems. Any suggestions or thoughts would be appreciated.

Thanks...... Brad

Dear Sir/Madam:

I am using Firefox Browser 102.15.1esr (64-bit) on a MacBook Pro Ventura 13.5.2.

I have been using the www.dictionary.com website for a long time, but recently when I attempt to go there, I keep getting the error message as follows:

Unexpected Application Error! FM.findLast is not a function

WM@https://www.dictionary.com/client.e12a2de6.js:36:305976 $o@https://www.dictionary.com/client.e12a2de6.js:1:26519 ka@https://www.dictionary.com/vendor.60d89d9a.js:1:864941 xu@https://www.dictionary.com/vendor.60d89d9a.js:1:921923 bc@https://www.dictionary.com/vendor.60d89d9a.js:1:910907 yc@https://www.dictionary.com/vendor.60d89d9a.js:1:910835 vc@https://www.dictionary.com/vendor.60d89d9a.js:1:910696 ic@https://www.dictionary.com/vendor.60d89d9a.js:1:907503 oc@https://www.dictionary.com/vendor.60d89d9a.js:1:906055 E@https://www.dictionary.com/vendor.60d89d9a.js:1:996565 P@https://www.dictionary.com/vendor.60d89d9a.js:1:997096

I tried clearing caches under Privacy & Security, but the problem persists.

(Meanwhile, I can visit www.dictionary.com on Safari and Google Chrome.)

Could you please let me know what is going on?

Thank you,

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.
