For the past 2 months I've found it very difficult to sign into my Hotmail account using Firefox. Microsoft keep telling me to use a VPN or another device. I like answering emails on my computer because of its large screen. I've tried signing in about 2000 times now. Firefox told me they can't help me because I'm not a Mozilla subscriber even though they own Firefox. Microsoft told me it's Mozilla's problem. Can anyone help me please. John in the Philippines.

Hello,

I'm writing because I’ve encountered an issue with the tab groups feature in Firefox.

Some time ago, after a browser update, I noticed a new feature that allowed me to group tabs thematically — I could name each group (e.g., "Study", "Work"), choose a color for it, and save and close groups to reopen them later. I found it very useful and used it a lot.

Last night, I decided to declutter my browser and closed several tab groups using the built-in menu. A bit later, I shut down my computer, but perhaps too quickly. This morning, when I turned my computer back on, Firefox was very slow to start. After a restart, everything seemed to work fine again, and the open tabs were restored.

However, all my previously saved (but temporarily closed) tab groups disappeared. In the tab group menu, I can now only see the ones currently open. I’ve searched through all the settings and history but cannot find any way to restore the missing groups.

Is there any way to recover the tab groups that I had previously saved and closed?

Thank you very much in advance!

Literally every single extensions I try to download says Installation aborted because the add-on appears to be corrupt. I don't know why because I just downloaded firefox.

Application error: a client-side exception has occurred while loading (see the browser console for more information).

where is the browser console? how do i fix it never had an issue with until the last two days?

Hi Guys, I have used Firefox browser to open and use Yahoo Finance for many years without any problems. On Wednesday 16th July 2025, suddenly, I could not download any stock charts. At first I thought it was a glitch with yahoo itself. However after a lot of searching and frustrating trial and error I seem to have pinpointed the problem to my Firefox browser. These charts will open as normal in Chrome. I have refreshed, uninstalled and reinstalled Firefox without success. Any ideas please?

Colin.

All of a sudden Firefox started to use alt+number (e.g. alt+3) to switch to that tab (i.e. tab 3 in my example).

Why? How do I disable this? It prevents me from typing any of the special characters that are located on alt + any number key. E.g. I can type the at-sign, not the dollar, or any such character which requires the alt-modifier and a number.

Yesterday I got a prompt saying there was an update available for download. Today when restarting my laptop and opening Firefox ALL of my bookmarks are missing!!! My bookmark toolbar is also empty. Where did all of this important stuff go? Please help me restore this my information asap. I am freaking out!

My bookmarks have all disappeared, and while I have tried to follow the instructions on the help page to restore them, nothing is working as it has been indicated that it should in the help instructions. I do still have my Bookmarks tab on my tool bar. When I click on it I get a pull down menu, which does have a Manage BookMarks bar. However it is not at the bottom of my pull down menu, but at the top. When I click on the Manage BookMarks bar, instead of getting an Import and Backup Button, my pull down menu disappears, so I can not select Restore to use to get dated backups.

In the same way, I can not create new Bookmarks. When I click on Bookmark Current Tab, instead of getting the white box to enter instructions, the pull down menu disappears, just as it does when I click on Manage Bookmarks. I have never had this problem with Firefox before in all the years I have used it. I have no idea what has happened.

SEVERAL SITES THAT I USE ARE NOT LOADING CORRECTLY WITH MY CURRENT AD BLOCKER. WHEN I DISABLE THE AD BLOCKER THE SITES LOAD NORMALLY. I AM NOW USING A DIFFERENT BROWSER UNTIL A SOLUTION IS FOUND.

Alternative search engines no longer appear when typing the stasrt of a search. Am able to set alternative search engine in settings but need to go back to settings if I want to use another one. This happened after a recent update - perhaps as much as a week ago.

When following the instruction to sync bookmarks on Android phone it leads me to items that are not there. Open Firefox mobile on phone. Ok. Hit the 3 dots drop down. Ok. Choose sync and save. Not there? I click my email and it shows sync. I click that and it shows the last time I sync my phone. 0 minutes. Ok. It shows a QR code to scan from the Firefox app. It instructs to click ready to scan. That's not there either. If instructions lead you down paths that are not present, the instructions are useless. Anyone else having this experience? Thanks..........

When using Firefox in fullscreen mode (via F11) on Windows or Linux, moving the mouse to the top reveals the tab and address bar. but this causes the page content below to shrink temporarily.

In comparison, Chromium-based browsers handle this differently: their tab and address bars appear as overlays, without disturbing the layout or causing any viewport resize. This results in a more immersive and fluid fullscreen experience.

Please consider implementing a similar overlay behavior in Firefox's fullscreen mode, or at least providing a toggle via about:config to allow users to choose between current behavior and overlay-style tab reveal.

A few months ago, my Firefox browser became corrupted and I had to delete and re-install it. My browser now works, and I don't have any issues downloading new documents, but every document I'd downloaded on my first browser that was labelled a Firefox PDF document is now corrupted. I can work around it on my own computer, but if I try to email the documents to someone else they just get the corrupted file. I've tried converting the PDFs into a different type of document and then reconverting them to PDFs, but the PDF version is still corrupted. Is there any way to fix this? Or is my only option converting everything to a different type of document?

Tried to go to Amazon (I have a Prime acct.) on my desktop. Mozilla asked for my PIN. I don't have my PIN. Mozilla said go to Settings and Accounts to add a new PIN. I went to Firefox/Mozilla settings and could not find Account in order to get a PIN. I tried searching in Settings on Account; nothing. I scrolled and clicked around and could not find what I needed.

I am old but far from tech illiterate. I've worked on computers since the mid-1980s. I've had this sort of layered problem with Firefox before. Firefox has been my preferred browser since the 1990s, I believe. I appreciate the concerns with privacy and safety in browsing. But I've run into this sort of problem a number of times. I need to know how to address the PIN issue. I'm happy to get a new PIN if I could only find a way in the browser's settings to do just that.

And, by the way, the password I had for Firefox/Mozilla would not work, though I have it written down, know my entry was correct, keep my passwords in a safe place. I had to open my account on Firefox/Mozilla with Google, which, of course, meant entering another password and doing verification via iPhone. And, of course, I ended up entering with Google and the entry was associated with my secondary email address. That, unfortunately, is not the email address my Firefox/Mozilla account is associated with. It is associated with my primary email address.

All of this takes way more of my time, the customer's time, than I intended when all I wanted to do was open Amazon and print a return label on a product I had ordered. The ridiculous process has left me pretty pissed off.

Frankly, I'd be happy to simply enter my Amazon password to complete the task I need to complete, but Firefox is in the way! Please make your security add-ons clearer and more easily worked with. And please let me know how I can get a new blasted PIN! Of course, I will evidently have to change my Firefox/Mozilla password, as well, since you will no longer accept my current password that, BTW, was made in the past 6 months.

Ugh! Just recognized that I have to wait for another user to volunteer some sort of advice on this. That just makes me madder. I excised my actual email addresses, primary and secondary, from this message because I initially didn't realize this just goes out to a generalized community to see if anyone has something to offer.

Getting closer to abandoning Firefox.
