Hello there :)

Please help me restore my browsing session :(

For the past several months I have been using Mozilla, and the feature to restore previous browsing session has always worked well. Even after I clear the most recent history or remove the most immediate cookies, this feature would still work e.g. after I restart my PC or just restart the browser. It would restore all the tabs I was using previously including the most recent tab I was on before the browser closed or restarted. However, this morning, I tried to clear my immediate browsing history as I usually do and the browser froze while I was in the process of clearing this immediate history (continuously displaying the pop-up window/interface for clearing history and not allowing me to do much else on the browser - I couldn't even click anything on the tab I was on, nor could I navigate to another tab and/or open a new tab; and only the close button, and maximize window button, and minimize window buttons were responding). After waiting for a while for it to start working again, I got frustrated and I closed the browser.

I then opened the browser again, but this time, it didn't restore the previous browsing session and didn't even take me to the last tab I was on.

What could have happened this time around? It has not behaved like that for this whole year.

NB: I have not done anything to the browser after opening it! I am still on the same page it landed on when I opened it (just in case).

Firefox will not allow my to post comments on Yahoo. I have no issues with Chrome or Safari. I get the following error message: Your comment failed to publish. Retry

my firefox youtube is broken, every time i close firefox, and open youtube, the comments and the sidabar wont load, until i clear my cookies and login. so that fixes it, but its not permanent. if i close or restart firefox, id have to repeat this process again. and yes, ive disabled all my extentions and cleared cache. and updated firefox.

Hi,

I am encountering an issue where Firefox throws an "Uncaught out of memory" error in the console, despite my system having ample RAM available. Here are the details of the problem:

• Error Message in Console: Uncaught out of memory
• Memory Usage Observed: Using about:processes, I noticed that Firefox's maximum memory usage caps at around 7GB.
• System Specifications: The machine running Firefox has 128GB of RAM, so there should be plenty of memory available.
• Firefox Version: 126.0a1

Given the significant amount of RAM available on my machine, it seems unusual that Firefox would hit a memory limit at just 7GB. I suspect there might be a bug or a misconfiguration causing this issue.

Can you please assist in diagnosing and resolving this problem? Are there any settings or configurations I should adjust, or is this a known issue with the current version of Firefox?

Thank you for your help.

I can't get Firefox to store bookmarks on my Mac since I installed Monterey 12.0.1. I managed to find some instructions on your trouble shooting page but they do NOT work. Hate to give you guys up, but unless y'all can help me fix this, I'll be moving on.

Tried to reset settings. Does not work. Went to about:config, than tab.mo / print.tab_modal.enabled set to false. Did this method before and it worked. Now this method does not work trying to get print preview back. Firefox is my web browser. I am in windows 8.1. Seems like Firefox did some updates again and now I can not get print preview back! WHY DOES NOT FIREFOX LEAVE WILL ENOUGH ALONE WHEN THEY HAVE SOMETHING GOOD? Bring back the old classic print preview button back and leave it. Now how can I get the old print preview button back???? Need help!! Thanks philm

Unfortunately, I downloaded “SaveFrom.net Helper” without reviewing it.

Since downloading it I have been receiving a alerts from “McAfee WebAdvisor” about “dangerous pages blocked”.

I was able to remove the “SaveFrom.net Helper” add on in Firefox, but am unable to remove the “Savefrom.net Helper” bookmark tab which has high jacked my normal Firefox Bookmarks.

I can no longer easily see my Firefox Bookmarks and have to keep opening the Firefox Application Menu, then select Bookmarks, then select Manage Bookmarks in order to see my bookmarks.

Can you please advise how I can safely remove the “SaveFrom.net Helper” bookmark tab which has high jacked my Firefox Bookmarks.

and not only that, when I click on sign in - it shows me a work email address that I rarely use - not my Firefox account / main email. I have to click NEXT then change email address from the drop down menu. I followed the setting attached. but it's still does it. I close Google tab, then go back and im signed out again! It's extremely annoying. How on earth can I fix this?

My tech info: Macbook Air Mac OS 12.2.1

Help continuously mentions something about clicking a "shield" to the left of the address bar, yet my up to date Firefox shows no "shield" anywhere i can find. Has an update obviated the need for it, and if so, do we have updated help files to reflect the new control for security, vpn and cookie usage?

Hello,

We are using Firefox on macOS to access web services that require Certificate Based Authentication. Our certificates are stored on YubiKeys PIV slots.

If we plug the token, open Firefox and access the website, it works just fine. The Certificate picker is shown and the OS ask for the PIV PIN to validate the access.

However, if we do the request when the token isn't plugged, Firefox does not ask for it, the website deny the authentication and the context is kept in cache. Requesting again the web site with the token added in between does not restart the certificate lookup and we are forced to close Firefox or move to a private window to make it works.

What is the proper way to avoid this issue? Is it a known bug? Is there a way to configure Firefox to always show the certificate picker even if no certificate are found and then reload the list of certificate based on connections events?

Thanks

Hello, I've followed Firefox's invitation to install and update the browser on my Mac. Unfortunately the new version is not compatible with OS 10 El Capitan, my operating system, so now I can't use Firefox at all. How I do get the old version back?

Thank you, Lars

I have the same problem as this person: https://support.mozilla.org/en-US/questions/1011006

but I have a windows 10 and the solution does not show up in the Taskbar settings. Is there an updated version for this? Here is the OPs original question.

"When I open a new Firefox window, it stacks it on top of all the others in the task bar at the bottom. I would like them to be BESIDE each other. It used to do that. Now I have to hover over the ONLY Firefox item on the bottom task bar and read the list to find the one I want to go to. This is a waste of time and tedious.

How can I change this?"

Crash? My Windows 10 tablet pro pop-up keyboard stops working for Hulu & YouTube so far. That's the main ones I'm on for that device. It won't keep popping up for me. Is there a way to be sure that Firefox messages always get to my main email? I want to be sure to get a notification, once someone can reply.

While using Yahoo email I tried to access the 'Notepad' page and get a message saying to Download a new version of Firefox to see the 'Calendar' even though I was trying for the 'Notepad' not the 'Calendar'. If I try for the 'Calendar' I initially get the small right-sidebar version fine but if I ask for the full page version I get the error message again. This does not happen if I access Yahoo through Chrome-browser. I have repeatedly done the download to no avail. (I have version 99.0.1). I am attaching a screenshot of the error message. Thanks for any help. No rush.
