Please help an old dummie? I have an existing FF install on a laptop. I would like to clone it (with bookmarks, settings tiles etc) onto a new PC. An article I read said open FF on the PC you want to sync. This is confusing! "Synchronising" is ambiguous, meaning 2-way. (but which way) "copy from" & "copy to" would be clear. I am worried I will synch(copy) from the new to the old....... effectively deleting/wiping out all my preferences in my original install. OR (preferably) Is there a way to just copy the whole installation from my original PC onto a USB stick & installing FF to the new PC from it? Many Thanks

This is my crash report https://crash-stats.mozilla.org/report/index/9ff24288-5f5b-4ad1-ac89-2b1180240805 please help on how to solve this

Fairly frequently I need to send files I receive in .txt or .pdf format to my browser to read.

I have attached hereto two versions of the same file - one sent to Firefox and one sent to Chrome.

Note that the screenshot of the Firefox version of the file contains loads of UTF-8 character translations that are incorrect and show up as strange characters instead of letters or punctuation marks, while the same file shown in Chrome is almost perfectly clear.

I am running Firefox version 127.0.6533.89 (64bit) in a Win 10 Pro 64 bit environment that is up to date as of August 1st.

This has been a problem with Firefox for a very long time and I would like to know if I have misconfigured a setting that has caused this.

I'm using openSUSE Tumbleweed and KDE Plasma. Ever since I updated to Plasma 6.1, Firefox crashes constantly when using Wayland. I'm not having this problem if I'm using X11. Crash reports are sent after every crash so I'm sure someone can reference these. When starting Firefox from a console, I got this message after a crash: "[GFX1-]: Wayland protocol error: wp_linux_drm_syncobj_surface_v1#67: error 5: explicit sync is used, but no release point is set"

Will this get fixed with the next Firefox update? Currently using 127.0.

Firefox keeps going off for from 5 seconds to about 20 seconds. It happens several times a minute. The screen goes blank and I can’t click on anything. Really aggravating. I would appreciate any help. Thanks

I have the strangest problem. If Firefox is closed and I do a speedtest in another browser, download a file, or do other internet activity I'm getting about 200-250Mbps d/l and 100Mbps upload. As soon as I open Firefox, whether I load a page or not, the upload speed stays the same, however the download speed drops to about 25-50 Mbps. This only happens on one PC, the upload isn't affected, and resolves itself as soon as Firefox is closed. Here's what I have done without any change in this behaviour;

• Rebooted
• ipconfig /release /renew /flushdns
• Removed and reinstalled the network adapter
• Enabled, disabled windows auto tuning and tested (slower disabled)
• Updated Windows
• Refreshed Firefox
• Uninstalled Firefox, deleted remaining folders from Appdata (Local, Low, Roaming) as well as the program file directories and "Mozilla" registry entries. Restarted and reinstalled. Issue immediately resumed when Firefox was open.

Also when connected to a VPN Firefox download speed increases to about 60Mbps and is consistent across other software. If I split tunnel another browser outside the VPN, it is still stuck at 60Mbps. If I close Firefox the speed increases.

This makes absolutely no sense to me, so I'm hoping someone can shed some light on this - but it does seem to be something Firefox is doing.

Thanks for any help anyone can provide.

As of a few days ago whenever I start Firefox the window appears with the Bookmarks sidebar panel already opened. I click the "X" on the sidebar and it will close - until the next time I start Firefox. If I choose Menu->View->Sidebar->Bookmarks and uncheck it the panel will close - until the next time I start Firefox. No matter how the Bookmarks sidebar is closed, it will always reappear when Firefox is restarted. Even if I switch to some other sidebar, Bookmarks will replace it on startup.

I've searched about:config and found no setting which seems to control sidebar behavior on startup.

I assume this is the result of some recent update. Is there no longer a way to permanently disable the Bookmarks sidebar?

MacOS 12.7.5 Firefox 127.0 (64-bit)

So, my old computer recently broke, but I luckily recovered all my files. I was re-downloading Firefox onto this computer, but my bookmarks and add-ons and stuff won't sync. When I searched for the solution to this, I saw someone having a similar-ish problem (https://support.mozilla.org/en-US/questions/1403774#answer-1563248), but they just said they had to wait awhile for it to sync. Now, I have a couple questions that I can't seem to get the answer to:

1. How long does it take to sync my data? How long did that person have to wait?

2. What if it never syncs and that person just got lucky? Is there some sort of alternate way to fix this faster?

I'd really appreciate help on this topic, but I'm not the best with computers. If anyone has had this problem, and figured it out, please let me know! I had a lot of bookmarks and a good amount of add-ons, I really would like to not lose those.

If you are currently using a normal window then there are ways to open a bookmark or link in a private window. But if you are currently using a private window then how would you open a bookmark or link in a normal window?

I have tried several things including pressing shift+enter or choosing "Open in new Window" from the context menu, but this just opens the bookmark or link in a new private window.

My current method is to copy the address of the bookmark or link then paste it into the address bar of a normal window.

But is there a more direct method of opening bookmarks or links in a normal window, if currently in a private window?

Thanks.

I'm using Firefox 127.0.2 on Arch Linux. In settings under General>Startup>"Open previous windows and tabs" is not checked. Under about:config browser.sessionstore.restore_on_demand is false, and browser.sessionstore.resume_from_crash is false

How do I get Firefox to give me a clean slate after restarting my computer?

When syncing between two different firefox instances not on the same OS or computer which of them is the syncing from and to?

If I have one instance where I have Firefox on a different computer and another on a completely different computer which of them does Firefox know it's the latest one to sync from?

Dear Sir or Madam,

Once again, Firefox is blocking my ability to go into X (Twitter). I'm guessing you guys did an update and changed the settings again. PLEASE FIX. Thank you.

Sincerely, Britt

Hi. i ran into a broken problem. sometimes when i bootup my pc and start the firefox, My windows crashes immediately. what shuld i do and how i can send the firefox log files to mozilla team?

I installed Firefox on a Macbook Pro with Apple Silicon, M3. The installation was from the Firefox site, I downloaded the dmg and then dragged into Applications.

I find that playback of media stutters, and is choppy--not sure of a better way to explain it. E.g., YouTube videos and the Bandcamp player have "stuttered sound". Opening another site in another tab can make this effect worse. Likewise, trying to run Google Meet in a browser window causes basically everything on the computer to become very slow.

This still happens even if I go to "about:profiles" and then "restart with add-ons disabled".

But if I switch to another browser, Safari or Chrome, then I don't have the issue. e.g. I can play YouTube in the background fine even when running some compute intensive task.

I have also tried turning on/off "performance settings" and the "use hardware acceleration" checkbox underneath it -- neither of those seem to have any effect.

Activity Monitor showed that at most Firefox was using ~4 GB of memory of a total 48 GB, and the memory pressure indicator seems to be quite low.

I have run Firefox on other systems (e.g. System76, older Macbook Pro) with multiple windows open each having 20-30 tabs and never had an issue like this.

It really seems like it has something to do with how Firefox is interacting with the M3? Happy to learn I'm wrong. And happy to provide more details about the hardware or my settings if it would help.

Hello, recently I've been having issues where if misclick anywhere on the title bar (even in the small space between bookmarks) firefox will minimize/restore when I didn't want it too. How do I disable this in about:config?

When I try to access an http:// site, the link is upgraded to https:// regardless of this setting.

This broke after a recent update to the browser. I cannot specifically say which upgrade, but it worked a month ago, now it doesn't anymore.

It may be worth noting that this broke in Brave (based on Chromium) at the same time.
