So I have the latest version of macOS Ventura, the latest version of Firefox, and the latest version of Roblox. Whenever I try to open a Roblox game from their website (yes, I know. Roblox now has the desktop app so you don't need the website to open a game), it opens the app, but not the link, which means it doesn't open the game :( Does anybody know how to get Firefox to open the link and not just the app? (Btw no hate on firefox)

My computer 'guru' reinstalled Win10 in order to correct a serious problem. ALL of my programs were gone and I was left with a raw Win10. 6/12/2023 was last date prior to the disaster. I reinstalled Firefox. Using the "firefox.exe -p" I can only find the default profile. I DO HAVE a full backup done using the Win7 Backup and Restore feature. How do I resurrect my most recent profile? I will need to find the files(s) manually from the b/u. When I did a Full Restore the bookmarks didn't appear. Where and what files am I looking for? The attached screen shots from the b/u may be of help. [removed email from public forum]

Gmail sidebar loads Calendar no error but sidebar empty/clear/white; Calendar only (other sidebar apps eg Tasks or Contacts load fine); Firefox only (other browsers eg Chrome or Edge no problem.

Tell me how to "re" install my previous version of 113.02 and then fix this bug. Don't know where to get "old" versions to download and will old version just "install" right over the version installed and keep all the bookmarks, etc.?

I installed what I thought was the "trust wallet" extension. It's not the real trust wallet. I had a little over $5K stolen in BTC, ETH, and SOL. Is there any way you can help me catch the individuals or somehow get back my stolen funds? Or any advice or direction will be helpful.

Firefox can sync anything except logins and passwords between different devices. I have selected "Logins and passwords" at "settings-Sync-You are syncing these items across all your connected devices", but it still dosen't work.

I am using Arlo security cameras which store the video captures as MP4 files. The Arlo app has video playback feature that works in Chrome or Edge but does not work in FireFox. From what I have been abe to glean from searches, Arlo uses HEVC Codec that FireFox either isn't compatible with or is lacking the codec. Any suggestions?

Youtube, sometimes, loads for ~5-10 seconds on average for no reason, doesn't load the video or audio at all. Extremely frustrating when I'm just browsing, it may not seem like a long amount of time but I shouldn't have these issues to begin with. Cleared cache, no addons are out of date or tamper with Youtube. Tried every fix I could find on the matter, nothing seems to have worked. Issue persists. I had similar issues with Kaspersky AV installed, so I had just uninstalled it. Prior to this newest firefox update, I have had no issues at all.

When I click a mailto link it brings up the GMail app. Instead I want the Yahoo Compose window. Several posts suggest various arcane methods. Either they do not apply or they require hacking. Has the situation improved?

How can I make mailto links go to the Compose window on mail.yahoo.com?

somehow i found old firefox history and files and when i tried re-add a profile history got ERASED!!!!!!!! is there a way to get history back?????? (files are from 2017)

I'm using Firefox on my Mac, and I'm really pleased with it so far, but I have a small issue on a specific website.

I can't share the website with you because it's behind the login details of my pension provider, sorry, but essentially the problem is with the hyperlinks to my monthly pension slips. When I click them, nothing happens, that I'm aware of, at least.

If I login to the same website using Safari (it's the only other browser installed), clicking on the link opens a preview of the PDF document on the open webpage (it doesn't open a new tab or window), but it's this that doesn't seem to be working in Firefox. However, if I click on the link and then the Download PDF link, the correct document downloads as expected, just no preview.

Is there a Firefox setting that could help with this, or is it more a compatibility issue in the website's design?

Thank you.

About 2 or 3 updates ago...after the update I can not clear all my web browsing history. I have my homepage set to Firefox's " about:preferences#privacy " I usually clear all the ' stored cookies, site data ' through the " Clear Data' button. Have it set to clear ALL data. Also clear " History " data and too ALL data.

Then I use " CCleaner " to clear any data that might have been left on my PC. 
It/CCleaner too has settings to clean Firefox's Cache, history, cookies, download history, session and more which use to work very well on clearing all data of web browsing.   That doesn't do it anymore. 
 After all the effort I go through after closing Firefox to delete/eliminate all my browsing history... through the manual tic-buttons IN Firefox... AND with the settings to clear cookies, site data and history upon closing.  PLUS using CCleaner.  
I ALSO close down/disable my 'Wireless Network' modem EVERY TIME I close Firefox  because I've had programs... AV program... that had stupid-non-disabling auto update that would connect... on it's own... to the net and not only check for it's update but downloads updates on every program update-able.
 But with all the work and precautions....
NOW when I click on Firefox to start a whole new session... remember all the moves I take AFTER the last session... It/Firefox asks if I want to continue with my last session and shows the sites I was at the last time.
If there is anyway to get... MY PRIVACY BACK!!! ... I would LOVE to hear about it.
I would LOVE to have my "Firefox 2.0. " back where/when there were no problems.
