Since the last update, 133 at least I believe that is the last update, I CANNOT LOG INTO Firefox for my PC. I have always used Firefox as my Primary Account therefore, once I have logged into Firefox I then log into my other programs such as Outlook.Live.com. Yes, I know that is a MS program. When I say I cannot log into Firefox.com this is what I mean. I click on the Firefox ICON in my task tray and Firefox appears only because I am NOT logged into Firefox. Then I am asked to Download Firefox for my PC. Of course, I know it is already downloaded and depending on the day I will receive a message saying Firefox is already downloaded or it may download it again. No matter my decision, I rarely have an opportunity to log in, unless I use a round-about way of going through Microsoft. Most of the time the application menu does not appear and when it does appear, and if Firefox allows me to use my credentials to log in, then I wait and wait and wait and the only thing that happens is NOTHING. I'm left staring at a blank screen. Since I've always used Firefox as my PRIMARY, after logging into it I then log in or open other programs I use such as Outlook.Live.com (yes, I know that is a MS program). After years of using Firefox I have never had to look at a blank screen and when I'm lucky enough to see the log in, I attempt to log into Outlook. But, I haven't seen Outlook in weeks. I have to use a round-about way of logging into Microsoft to log into Outlook, sometimes that works and sometimes it doesn't work. It's as though Microsoft and Firefox have found a way to merge their programming. As you may imagine it takes me over an hour to use the programs I need. 'AND, here is the icing on the cake. Mozilla Firefox no longer monitors Trend Micro Security which I have used at least 15 years. At one time, Firefox did monitor TM as an add-on but no longer, and when I checked to see the latest update you were showing, it is obvious you are not keeping up with TM's many updates. I have received some very strange messages from websites I previously log into on a daily basis, such as Grammarly and Pocket and have been redirected to a Microsoft page indicating I owe money, which I DON'T so that was another waste of my time clearing that up. Now, I have gone days without logging into my PC out of sheer frustration. I don't know what else to do and now I'm not protected with a Security Program although I do update and run it everyday. Yes, I am aware of Microsoft's firewall but I'm not sure how well that is working since my PC is now out-of-date. I suppose I could start a Go Fund Me page to earn enough money to buy a new computer...lol I desperately need help. BUT, I CANNOT understand your computer talk, I need things explained to me in everyday language. I hope this makes some sense. Rhonda Caywood

Certain items in the browser black out completely. For instance, when I open a google sheet; in the first 3 seconds, I can see the spreadsheet. Then, suddenly, it blacks out. The same is true when I try to open pdfs. I'll add screenshots.

I have an account with Chewy. When I try to access the link to "My Pet" I receive this message:

400 Bad request Your browser sent an invalid request.

I don't understand why or how to correct it.

I did not set a primary password but they I'm constantly asked to enter it? I can't reset it because it'd delete all the saved passwords which I want to view. Is there a default primary password?

Wikipedia render Thai fonts correctly. But it seems to render Latin texts and numbers in "TH Charm of AU" font for Thai articles, which I did not set anywhere in the browser (and my operating system). Ticking "Allow pages to choose their own fonts, instead of your selections above" does not fix it either. But it renders fonts correctly in English version of the same article. (See the attached images).

Any ways to fix this?

Thanks in advance.

The middle mouse button press has no response.,Can't scroll the screen.,Other functions of the mouse are normal.,In other browsers, the middle mouse button is all normal.,What is the reason for this? Windows 11 brand new, new installation of Firefox.

Good morning, after today's FF update - right click dropdown menus are terrible! Nothing works for me... Opening new windows, new tabs, adding to bookmarks, copying, pasting, etc... How can I turn it off because I can't use it. I need to have a menu like in version 133.0.3. If I can't change it, I will have to change the browser because I can't use it! Thanks for your answer and best regards! Arthur

Hi all,

I’ve been using Firefox for a while now, but coming from Chrome, I’m finding some aspects of Firefox’s cache management and tab behavior a bit inconvenient, and I wanted to share my thoughts.

The issue:

When I restart Firefox (version 133.0.3-1), it loads webpages from the disk cache, which is fine because I’ve set browser.cache.disk.enable to true and browser.cache.check_doc_frequency to 2, it will always make a request to the server on restarting Firefox with the default value of 3. However, the problem arises when I open new tabs — they also load from the disk cache instead of requesting fresh content from the server.

What I’m looking for:

   A way to have Firefox:

Load webpages from the disk cache when restarting the browser (which I want, and I have set browser.cache.disk.enable to true for this). But always make fresh requests from the server when opening new tabs, no matter what the cache settings are.

In Chrome, this behavior is more intuitive — it loads from the cache after restart but always fetches from the server for new tabs, which I find to be much more reasonable.

I understand that about:config provides settings like browser.sessionstore.restore_on_demand, but adjusting this option makes Firefox fetch content from the server for all tabs, including those opened after a restart. This doesn’t seem like a perfect solution because it takes away the ability to use the disk cache after restarting the browser.

I would really appreciate it if Firefox could offer more granular control over this behavior, so users could get the benefits of both caching and real-time requests based on the type of tab (restart vs. new tab).

Thanks for your attention, and I hope to see some improvements in future updates!

Over the past couple weeks of updates, the about:processes page is now missing several elements, such as the memory usage, CPU usage, and the close (X) button for each process/tab. See attached screenshot. Normally each row would show the memory, cpu, and if it's a closeable tab, the X button would be on the far right upon hover.

Let me know what other info you need to squash this bug. Thank you!
