Since the settings haven't given that option for years, the best way to have a local file as the new tab page was using autoconfig.cfg + autoconfig.js, as described in this thread: https://support.mozilla.org/en-US/questions/1251199 But since the most recent update (v136.0), this stopped working.

The New Tab Override add-on has its own issues with using local files (can only load a .html file, no local CSS/JS, can't give a blank address bar for me to search in), so it doesn't solve the issue either.

This is very important to me, and others have been asking for this feature back for years. It feels awful to have the working solution stop working, in the browser that's supposed to be open and customizable.

According to Firefox Help, "After you have defined and set your Primary Password, you will be prompted to enter it once for each Firefox session, when Firefox needs access to your stored passwords." But since updating to version 136.0 I get asked for my Primary Password even to see my home page. Why is this?

The icons on my home page suddenly became significantly reduced in size. Sure, I can tell what they are, and I've increased the text size for their identifiers below the icons. But they are now so small as to be not pleasing to the eye. How can I put them back the way they wuz?

My Firefox browser has been crashing for a while now (Years). It's fine playing YouTube and BBC iPlayer but when I advance the time marker to a different part of the stream or video, it crashes. It also has a problem when playing slots. It seems to crash a lot making it impossible to play.

I have tried using Firefox in Troubleshooting Mode but the same things happen.

Here's the crash report ID

Many thanks in anticipation and I hope someone can help me fix these issues.

How do I get the PDF viewer to work again? For years I have used the setting "save" to automatically download. Now I am unable to view them without going in and changing the settings to "open in firefox". I would like to continue to use the save setting without having to constantly change this back and forth. When I click to open the file, all it does it grey out.

Hello,

I'm new to Firefox after changing from another browser.

I am looking for a setting to turn on notifications from sites such as Instagram to notify me with a pop-up window from the web browser.

Is this not available on Firefox?

If not available, I'd like to suggest this as a new feature.

If it is available, would someone help me find this to turn on when I signed into Instagram? It did not ask me if I wanted to turn on notifications.

Thanks

After briefly succumbing to the ToS hysteria, I decided to switch to Librewolf. It took a while, but I got logged into sync, set up my extensions and copied over my cookie exceptions and custom CSS.

Some of the data that came over from Firefox sync seemed very wrong or out of date, most notably the settings for container tabs. No big deal I thought. I'll just manually edit the discrepancies. Once I had everything set up the way I like it, I looked up a guide on how to sync my current configuration with the cloud and followed the steps.

Phew. Time to watch some YouTube to relax. Problem is that when I finished a video and tried to watch another video, I was logged out and my site settings had reverted to default. I figured the cookie settings were wrong, so I went to the settings page and saw the behaviour outlined in the video I posted.

I've been trying to get this working for over a day now. I've tried resetting Firefox, creating new profiles and doing a clean re-install using "Geek Uninstaller" to make sure everything is removed first. I've tried 3 different forks of Firefox and all 3 of them do the same thing. After I re-install everything, I open the browser and the first thing I do is go to the settings but it's still doing the thing I showed in the video.

The fact that the data on my Firefox Sync is so old has me wondering. Why won't the cloud data update itself anymore? Based on the state of my containers, the Sync data is more than a year out of date. Could there be something wrong with that data that broke my browser when it downloaded?

I'm going to try and get hold of another computer later and try syncing to that to see if it breaks that browser too. I'll update this post when I know more.

Thanks for reading all this.

P.S. I'm typing this using Edge because my Firefox is so badly broken.

for some reason Firefox will not connect with my ATT/Ameritech account for email. It shows up that its an unknown error with AT&T. I can log in in troubleshoot mode, just not regular mode.

When I try to compose a new email, or reply to one, the pane opens to compose the email, but immediately closes before I can enter anything, reverting back to the Inbox. A new, empty draft gets created. But there is no way I can create a new email. Problem does not occur on other browsers. If I open a "New Private Window" and sign in to Outlook, I can then create the email there, but after a while the same problem occurs in that window too. Tried clearing Firefox cache temp files and cookies, but that did not resolve the problem. Using web based Outlook, Windows 10. Firefox is up to date.

Any suggestions?

Customization:

I want to change the Microsoft desktop icons on shortcuts to a number of internet URLs. Unlike with other shortcuts, this is not possible with Firefox. Too many of the same icon are confusing. Seems to me it would be a simple and useful option.

Hi, In the last hour FF has stopped working completely. I made the mistake of using Ccleaner, which is probably the problem, I haven't had issues cleaning before, though I usually check the registry before deleting and don't recall seeing any entry for Mozilla (I may be wrong, though).

Firefox was working fine a couple of hours ago, but now it won't open at all, except in admin mode and then it won't open any links or tabs, not even settings. I've uninstalled FF, deleted the folder in the Programs folder, and reinstalled it from scratch, but there is no change (the one difference is that it wouldn't open in Admin after before I reinstalled it). Waterfox doesn't open either, but Thunderbird seems to work with no problems.

Thanks, Matt

does Firefox no longer support sites like The Guardian, like the Atlantic, other news outlets. it never lets me sign in but returns to the home page after signing in with email and password. What do I do?

I have check spelling enabled in Firefox. I use Firefox in English for technical reasons, but I write most of my emails in Hungarian. I was prompted to install a dictionary addon to be able to use Hungarian spell checking. I did install that addon, however I still can not choose any other language to spell check in but English. I would like to resolve this issue. My Firefox installation is very fresh, I am leaving Chrome in favor of Firefox and would like to stay. What I would have expected is that I install Hungarian, then the spell checker automatically identifies the language pack it needs to use.

I use a website in the UK alljigsawpuzzles.com The page loads fine and freezes with the firefox browser. Other browsers work fine. I have been unable to determine if a setting is the problem. I use https only. When I removed this setting, it allowed me to scroll for a few seconds and then froze again. Do you know what the problem is? It's true they recently upgraded their website. Is there a setting I need to change? Thanks! All updates are up to date.
