Firefox Community Forum

I have been a user of Firefox for many, many years (it is my default browser) and as of today I am extremely upset with you. Once again I go to use my favorite browser and all my bookmarks have been removed. THIS IS THE SECOND TIME SINCE THE NEW YEAR 2026.

I spent a great deal of time putting the bookmarks together that hold all the links to clients and their respective sites, along with all the places I have applied to and was about to apply, and today, again, they have all disappeared.

So, give me a reason to keep using your browser? As of this point, I am going to move to another browser and begin setting up all the bookmarks that I remember ... thanks for what seems to have become a HUGE problem with Firefox and blowing away my bookmarks and making me reset everything.

I have used Firefox when everyone told me to move to another because I believed you were the best at protecting my browsing experience and you didn't disappoint. But these last two times you have removed so much of my time I am at a loss as to why I even bother with you now ... besides, you have removed my Dad's obituary link and I'm not sure I will ever trust you again.

A, once, true believer in your ability to protect me.

If I try to log into my router at 192.168.1.1 I get a message that says "Warning: Potential Security Risk Ahead". I expect that, but when I click on the Advanced button it doesn't do anything. Works fine with Chrome, so not my router or anti-virus. ???

Windows 10 Firefox 148.0

I've always used firefox

Recently it seems to me that a lot of sites don't seem to recognise me, so I have to do multi step logins.

Paypal for instance. I don't save the password, I type it in each time, but now it insists on sending me an SMS in addition

My guess is that FF is deleting some cookies that I'd rather it didn't. What can I do?

Thanks

All of my bookmarks; hundreds of them, disappeared from the folders that appear along the top of the task bar and the folders are now empty. I cannot locate a backup file which is supposedly saved automatically and the appearance of a folder on my desktop titled "old Firefox data" doesn't help resolve the situation. I need help recovering these book marks if possible.

Dear Support Team,

I am currently experiencing a very frustrating issue with Firefox. I have been using it for many years, and it has always been my preferred and most comfortable browser for my daily work. I depend on it heavily, as all my bookmarks and other important information are stored there.

Over the past few weeks, Firefox has been crashing more than ten times a day. I have already tried all the troubleshooting steps suggested in forums and through AI-based support, but none of them have resolved the problem. I also attempted to install and use the Firefox Beta version, but the issue still continues.

In our environment, other users and devices are not encountering this problem, so it does not appear to be related to internal firewall or antivirus restrictions.

Could you please assist me in troubleshooting this issue? I have attached the error screen that appears after the crash along with the crash report for your reference.

Best regards

Good evening. I have had to install my FF after a system repair. I have everything set back except when I click on a link and hightlight an item with my mouse and right click it opens a new tab. But before where it would just open it changes to the new tab immediately. Under settings I have the 'when open new tab switch to it immediately' unchecked and I was directed to four settings on about:config including browser.tabs.loadDivertedInBackground to set to true. I did and the behavior did not change. Any suggestions would be helpful. Thank you.

The new version of Download helper is uncommissioned for YouTube. I have tried everything including reinstalling, clearing cookies and catch etc. How can I just revert back to prior version as this seems to be a degraded version?

when clicking on an icon that is going to send an email, Firefox defaults to Outlook. I do not have Outlook nor do I want it. I want Firefox to default to my Yahoo mail account. I checked the Settings/General/Applications window for the mailto option but it is not there. How can I change the default mail from Outlook to Yahoo in Firefox (using windows 11).

bold textI have created a new profile, uninstalled Firefox and reinstalled, flushed the DNS, always deleted cookies et al on closing. When I try and sign on I get a msg saying site unavailable, but when I go to the laptop sign on without any problems. Also on my desktop if I use Edge to logon to the site I am successful.

In Firefox's Task Manager, how do I know which tab is using which subframe(s) process?

For example, let's say I open Firefox and with only one single tab open, I open the following web page: https://audioplugin.deals/product/best-of-zampler-collection/

That page apparently includes content from several third-party websites because when I open it, Firefox's Task Manger shows processes for the following:

https://audioplugin.deals https://cloudflare.com https://google.com https://hcaptcha.com https://soundcloud.com https://stripe.com https://stripe.network https://stripecdn.com

The process for "https://audioplugin.deals" is the only process with a tab. All of the other processes are subframe(s) only, with no mention of which tab is using them.

With only one tab open, I intuitively know that all of these processes must be used by that one tab. But like most people, I browse using multiple tabs, and once you open multiple tabs, it becomes (as far as I can tell) impossible to determine which subframe(s) process is used by which tab. This makes it impossible to determine which tab is behaving improperly or erratically when there are issues (for example, when one of those subframe(s) processes is consuming an unreasonably large amount of memory or CPU cycles).

I am just an average end user and want to alert you to my problems and would love a solution. I am sorry that I don't have the kind of specificity in the details which might help (I am too busy doing other things and when firefox becomes too much of a pain, I generally close it and switch to another browser). I am providing my general observations. On my updated windows 10 64 bit system, firefox v148 seems to have made the browser unusable for me. Other browsers do not suffer similarly (Chrome, Edge, Opera, duckduckgo). I have had these types of issues with Firefox in the past, but they resolved with prior updates. I am at the point of switching to another browser - I hate the thought of it, but Chrome seems to be the most stable and functional. Symptoms:

• Firefox browser and the computer gradually become slower as firefox starts hogging cpu and memory and starts using a lot of power
• extensions stop working - eg, Keeper extension stops filling fields or fills incorrectly, Malwarebytes extension seems less responsive, running background sounds makes things even worse (https://www.mynoise.net/) and web pages with continuous updates (eg, map.purpleair.com) stop working altogether
• other pages stop loading, load with errors ('bad connection') or load very slowly, especially, but not always, those with more security, eg, my bank or retirement funds sites.
• after i close Firefox and start fresh, symptoms resolve, then rinse and repeat.

The previous version worked great and seemed to solve similar issues I have had with earlier releases. I assume the last stable release for me was one of the 147 versions. but when things are going well (which is most of the time), I'm not watching closely, or at all.
