Diễn đàn hỗ trợ Firefox

I have noticed that few websites are not running properly on my firefox.. Youtube being the most prominent since i use that a lot. Some times it disables click on links and other time it does not redirect to any other page. if i open the page in new tab it only works then. I have tried reinstalling the browser but it doesnt help. It could be related to some update maybe cause it works fine on my other machines.

I had to format ( factory reset) my laptop. After installing mozilla, and sync my account is like new. All previous data i.e. Login, password, bookmarks, etc all are missing and i tried about:profiles method which is also not working. What should i do to recover my old data?

The first time I noticed the Megabar (I believe it was FF75) I absolutely hated everything about it and ruins the experience using Firefox. I am also not alone in this matter because as soon as the change was established, communities popped within hours to fix the problem. The old way of fixing this eyesore of an issue was the old about:config and changing around the settings then VIOLA! back to normal. Now after the update to 77, the Megabar is back and forced down everyone's throat and the old about:config is no longer the fix to this terrible experience. Literally after an hour of this trashbar being up, videos and guides popped up to try to fix it. Whole communities have been formed to hate this feature and ask Firefox to change it, or at least make it optional to go back. My question is, looking through google has only come up with the chrome.css(?) fix to this mess. Is there any way to change it back to the old url bar without having to go through the chrome.css fix or just uninstalling and reinstalling a previous Firefox or do I have to just migrate to another browser like Opera or Chromium?

Via "about:config" the "signon.management.page.fileImport.enabled" option is enabled. I tested it on a fresh install on another machine just now, and it does add the "..." button - however, the option to import and export from file are completely absent - only the options to import from other browsers are available.

SEE SCREENSHOT

The option you can see in the screenshot, that was available until this week apparently, is no longer available after turning it on. I rely on this feature at my Job, when we image machines with logins for our users.

I need this basic functionality of all web-browsers or we'll have to switch to another one. We do not allow the users to Sync their accounts with FireFox/Lockwise, as we do not want the passwords being taken to other locations/pc's where they have signed to Firefox.

Please help - Thank you.

Firefox keeps displaying '400 Bad Request Request Header Or Cookie Too Large' when trying to read articles on www.bloomberg.com.

It only happens when using this site and only on Firefox and not on Safari or Chrome.

How to fix this and be able to use Firefox as default browser for this site?

I'm trying to access a website, but I keep receiving the same error message over and over saying "Access Denied". This is so strange since I had no problems accessing it at all yesterday. Can anyone help me?

There should be a screenshot of the error message below.

I discovered that yahoo search was sitting in my firefox browser...laptop windows 10. I followed instructions to refresh firefox. It seems to be successful. Should I do anything else or just carry on?

This has just recently started with this constant crashing of my Firefox. I'm doing computer work and then it crashes. I submitted the crash reports that were not submitted this morning on December 02, 2020. Yet, two of the crash reports failed to submit.

When I attempt to login to a captcha protected account it won't stop with the verification. I have to answer the captcha picture puzzle 30 or more times. After this occurred on several different sites I finally tried Google. The captcha worked the first or second time.

What gives with this? I dislike using Google, but FF may leave me no choice.

Windows 10 (latest version)

Most of the time it is when I am using Facebook and have more than one tab open.

At the moment it's a waste of time having tabs as options because I can't use more than one at a time or else every single page comes up with this error... a web page is slowing down your browser

Does anyone have any bright ideas on how to get it to stop - I have search the net and changed and tweaked a few settings but nothing has made any difference at all.
