Keep getting the message on new Tab page..."500 Internal Error". Tried a search of it, found correction suggestions...did a soft & hard reboot=nothing. Tried finding the Firefox Cache, that said to delete, but can't find that file in the Settings tab in Firefox. So can't do any searches in Firefox for 2 days now. Can you help to resolve this? Or, do I have to delete Firfox & go to another browser?

I have a very fast internet connection, 200 mbps and everything else on both my laptop and my mobile phone are working fine but Firefox is very slow. Pages load ok but videos will play for a short time and then freeze never to continue and downloads are painfully slow, 2 to 4 mbps. Edge and Chrome download normally and videos play with no issue. I need this fixed or Firefox is going bye bye!

Each time I connect to the Sam's Club website I get a popup box that says "Let us know your human (no robots allowed)" even before I try to login. There is an "X" in the upper left corner of the message that I can click on twice and the box goes away. I then can click login and my password saver fills the boxes at which time I get the same box. I click again on the X and a message says there is a problem, try again later.

Current version of Firefox on Windows 11. Menu bar hidden when Firefox started. I have tried every setting suggested and understand how to turn it on, but next time I start Firefox, menu bar is hidden again. Reinstalling Firefox -- no joy. Restarting in safe mode -- no joy. Help!

Recently after signing in to Pocket, all my tags disappeared. They can still be seen at each individual entry, but not on the list of tags. Any new tags I added also don't appear in the list of tags, which is completely empty. Searching for tags also gives no results. I tried to log out and log in again, but it had no effect.

I have been using Firefox for many years and I have never had problems, until now, out of nowhere Firefox closes and the little window opens that the report is being sent to Firefox, but I can no longer restart or open Firefox, until I reset the computer, This can happen one, two, three and even four times a day, making it very uncomfortable to reset the computer.

I have already tried many ways to solve the problem, from completely uninstalling Firefox and reinstalling it, I use very few extensions, I already disabled WebGL and also disabled hardware acceleration, nothing has worked, when Firefox closes, I cannot open Firefox Developer either and That browser was not even open at the time of the failure with Firefox.

In the last few days whenever I download a PDF file instead of it being displayed in my default PDF read Firefox (version 121.0.1) takes over and displays the contents of the file. I do not want this, I prefer my PDF reader! How do I stop Firefox trying to take over this function? (other than converting to Chrome)

My account names to all of my email masks have disappeared. Why did this happen? How do i get them back? Now I have not idea which email masks are for which accounts.

Is this really Mozilla or Google playing dirty? I ask because the site I was trying to access suddenly has stopped working on other browsers, so I thought I would try it on Firefox, and this is what happened. I do not have the security key it is asking for so I cannot even log into the site. The site support told me that they recommend Google Chrome. It seems too coincidental that it suddenly stops working on other browsers and Firefox won't even let me login. Nor has it EVER asked me for a physical security key to access any site before.

With color perception limited vision, I cannot distinguish default colors for visited/not-visited link colors. I tried changing colors in Settings via:

Colors / Override FF's default colors for text, website backgrounds, and links:

I changed the colors to what suits my needs BUT just changing those colors ALSO put focus(?) lines around various texts and randomly changes colors elsewhere in arbitrary fashion making my changes unacceptable. What am I doing wrong?

I am not stupid, but I do not understand the langauge used in describing "modifications." It would be useful for people in similar states of lack of knowledge to have at least maps/legends of web pages explaining the arcane language of webs.

I love this addon, but sometimes it doesn't respond. it hasn't been updated since 2017 and the support page is inaccessible.

Back To Top for Firefox (WE)

Is there a something similar available?

I had trouble with pages not gully loading before and videos not playing and now the videos don't play at all. No matter refreshing, closing Firefox, blocking YouTube shenanigans with ublock (I also get this problem on steam) or unblocking. I would really prefer that I don't have to reinstall AGAIN. I already had to do that not long ago. Can anyone help me with this problem...? Thank you

1. 1 I set the Manage Data tab to 'Allow' for sites I want cookies saved for. This sets the http and https addresses for the sites I enter.
2. 2 I set the same sites in the 'Manage Exceptions' tab so that these sites do not have their cookies deleted.
3. 3 Save Settings
4. 4 Close and re-open Firefox. All cookies are deleted.

I suspect this is a bug?

Cheers.

I've written about this before and never got a working answer. I have to use Chrome or internet explorer for some work because FireFox won't open the sites. This problem hasn't been fixed by I clearing cache and cookies as recommended back when I first asked a year or so ago.

Now the latest website I haven't been able to use is the Post office! USPS.com -- If I try to track a mail piece using my tracking number the site can't bring it up. The site tries for long time then tells me to try later. When I try with another browser such as Chrome, the result is there within a couple of seconds. It looks like I'm going to have to leave FireFox which I hate as I've used it so long - over ten years at least.

I can no longer access my online banking at td.com - the server returns the following message: "Bad Request - Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

The online banking works normally with Safari. Please help me fix this quickly.

Thank you.

Hello, I'm a subscriber to the www.investors.com. when i click on a stock symbol, the stock chart takes a long time loading. when they do load, no grid shows on the graph. I do not encounter the similar problems when I use MS Edge or Google Chrome. Can someone help. Thank you.

In HTTPS-Only mode I quite often get a message that the site does not support https but when I Continue the page I land on is a https page. I can't understand what's happening here: does the site have a https page Firefox can't detect or is HTTPS-Only creating the https connection for me, or is it only pretending to be https and there is no real extra security? If someone could enlighten me as to what's happening I'd be most grateful. I have a couple of screenshots to show what I mean, but perhaps you know exactly what I'm talking about anyway! I'd add I can't see anything in the Help articles that seems to deal with this situation, but perhaps I'm just being a bit dense (not unknown!). Hoping you can clarify this for me.

Dzień Dobry,
