There are so many reasons why people don't want AI on Firefox. If I wanted AI, I'd go and use a chromium browser. I came to Firefox to get away from AI bull, not to have it shoved down my throat here as well.

If the new AI changes roll out I'm going to be finding another browser that won't risk my privacy just for a machine that only works half the time or add to AI centers destroying the environment. Thanks!

I recently opened Firefox to see a new flagged warning under my toolbar that says "The security sandbox is disabled. Your configuration is unsupported and less secure."

I have gone into about:config and adjusted every security.sandbox element to see if that would change anything; it did not.

I am running on Windows 11 Home so I cannot install or properly run Windows Sandbox.

I would either like a solution to enable the sandbox once again, or just remove the notification from the toolbar.

The 2-year-old support page "View synced tabs from other devices" gives 2 methods for syncing all your tabs from one Windoze FF to another. Neither one does anything at all for me now. The "right-click on the device in the sidebar" sounded SO promising, but it does not cause anything at all to happen. And checking the "sync tabs" box does indeed make them all show up in the sidebar list, but does not open anything. So besides clicking on each of the hundreds of tabs listed, how can I do this, or is it just another FF functionality lost to time?

I've noticed over time Mozilla has become less focused on consumer privacy and more focused corporate interests.

My questions are to you developers of Mozilla.

Would you have reached success in the past using this model?

I've noticed a corporate trend of brands being consumer friendly in the beginning of their history then over time snubbing the customers in favor of getting paid to sell data to corporate interests, data brokers and government entities.

Should we trust you?

I've been using Firefox for almost 20 years and anyone can agree that this browser isn't getting better over time.

Can you provide a list of all the third parties you deal with selling our data?

I have a nagging feeling this isn't the browser it used to be and some of us will need to change to a less corporate focused browser to protect our data, since it seems you aren't interested in that model anymore.

I don't know if this is the proper topic, but I'm not sure what to call it. For the longest time I've had an issue with the settings being reset every time I open the browser - all my add-ons are off, all my configurations return to the original state, every single time. I have to manually turn them on all over again every time. Does anybody else has the same issue? Can it be solved somehow? Do I need to redownload Firefox or something?

The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

My settings: Downloads: save files to: [custom default folder, unimportant] Always ask you where to save files: ENABLED

Applications: PDFs: Open In Firefox (because when the browser has such a nice built-in pdf viewer of course I would like to use it)

Expected behavior: Browser will open the dialog box for where to save the pdf, save the pdf, then open it in the in-browser viewer from the location it just saved to. Or possibly: save the file to TEMP and then open it in browser, I can see the argument for that behavior, though it wouldn't be my first instinct.

Actual behavior: Browser blindly saves the pdf to the specified default folder, then opens it in the in-browser viewer.

What is the actual point of the ALWAYS ask checkbox here? From what I can find extant on the forums the devs somehow don't seem to consider this a bug, so does anyone know how to wrangle the config page and/or some kind of extension into producing the actual logical behavior for these settings?

Please stop adding AI to your browser. It is making it slower and is a data privacy concern for me as well as many others. If you do not remove them I will be switching browsers. AI is not only bad for the environment, it does not even do the features you want it to do correctly. Please remove AI from firefox, i have been using this browser for years and would hate to leave because you refuse to remove AI features nobody asked for.

I opened a profile that I had just used recently to a blank tab bar. I closed it and the sessionstore-backup folder did not have a recent backup, The most recent about a week old.

Just for testing, I tried to restore with one of the upgrade.jsonlz4 file, about 2 weeks old, but it also had no session. I then restored one that was 2 months old. That one had a session

Now, Firefox no longer generates the upgrade.jsonlz4 files

When using Firefox and clicking on a link oftentimes instead of the link opening in Firefox it opens Microsoft Edge. I have Firefox set as my default browser. Other than uninstalling Microsoft Edge is there any other solution to this problem? My OS is Windows 11 Pro.

One of my jobs requires me to download work related documents on my personal pc. I would like to assign the website of the platform we use to download those files in a specific folder so i could delete them easily afterwards. Are there any plans to add such a feature to the browser? Is there a way to do it already? (without having to use the "always ask" option) Thanks in advance. Cheers from Uruguay

Hi there I have the problem that my firefox can save any file or download on my other drives since they arent event show as an option. I did a little research and read that by default in linux for security reason was unable to, but asking in the official forum of my distro (cachyos), they can save thing in other drives with no problems.

So i wanted to know why i dont?, my firefox installation is native at installing the dristro and having all perimission but it cant see my drives except the one is installed to (and where my OS is).

The only thing different i actually do is the folder where my current user info is saved, i moved the files from my user but with the files i had from my old windows session to impor my saved sites, favorites, etc.

Can you help me to be able to save files or images on my other drives?, thank you for time.

I recently heard about Mozilla's potential future plans to increase the browser's AI features, and wanted to voice my concerns about this.

I avoid using AI due to environmental, privacy, and ethical reasons, and one of my main motivations for choosing Firefox over another browser is specifically because of the option to turn AI features off. (And I believe this is the case for a large portion of the userbase.)

If Mozilla opts to push for more AI implementation within Firefox, I will switch to another browser.

How do I confirm that the AI that was recently put into the browser is not working? I want nothing to do with this technology, if it is not able to be disabled then I will switch browsers.
