When I start to type a reply to a Facebook post, the page scrolls down so that the line I am typing disappears one line below the bottom of the screen. I have to scroll down to see what I'm typing. Also, it jumps down the same way whenever I hit the backspace key to edit what I'm typing.

I discovered a previous (archived) post on this forum that suggested using "about.config" and making sure that the value setting for browser.backspace_action is equal to 2. But that didn't change the annoying behavior. Is there any other value I should try? It's not clear what the number means.

Nor did setting browser.backspace to true (or to false) seem to help with the unwanted jumping upon use of the backspace key.

This only seems to happen with Facebook, but it's quite annoying.

After firefox update to 100.0 - i can't use any of my addons, and cant install new one. All my current updates appears in "disabled" status, and there's no "enable" button. I have many addons, so it's the global problem.

Also, i can't install any of updates from addons.mozilla.org, i get message "Installation aborted because the add-on appears to be corrupt". All addon xpi files are downloaded without problem using "save as", also, after clicking "install" on addons website i see download progress.

Please help to resolve this issue!

Until recently, I resisted allowing updates for Firefox because of the announcements of changes to prevent access to some technical kinds of website which I use. These include the public websites of the Paris Observatory which include useul informational ftp pages with important text, data and software files.

  I did recently allow a Firefox update, and now I find that I am cut off from access to these ftp pages. 
  How can I re-enable access to ftp? If it can't be done in the new version of Firefox, how can I return to an older Firefox version that does allow such access?

I have installed two dictionaries, "English (United Kingdom)", and "French". However, when I go to check a spelling, (right click/Languages over the suspect word), I am offered a third dictionary choice, "English (United States), which I do not want. I have removed the US dictionary and even the language pack but the menu item persists. I can find no way to get rid of it.

Please advise

There are a number of old threads regarding this and having worked through them it is still unresolved. 1) I have cleared cache/cookies 2) I have disabled all extensions 3) I have turned off tracking 4) I have tried in safe mode - still the same.

This is not just on one website - it is on ALL that have Facebook feeds. It is NOT just on my laptop - I have asked others to try - they have the same result - blank page. ...so please don't suggest re-installing Firefox!!

An example is: https://dragonsdensoftplay.co.uk/News-Events/news-events.html

The feed works ok in other browsers.

Thank you

Hello :) For some time now my firefox doesn't allow me to preview PDFs. If I open it, it gets downloaded at the same time which I don't need. I already tried the thing with renaming the handlers.json to handlersOLD.json but it didn't work :( does anyone know how to fix this?

The latest example is the button to sign into LinkedIn. It is not working in Firefox, but it does in other browsers. I have other examples just from today. I have used firefox as default for many years. I assume this is a security thing, but these are basic links. I have no add-ons or other complications. Most times, I do not even realize there is a problem, but when I feel something is wrong, I try another browser and it works. Thank you.

Hi and thanks for your good app The following website is not loaded in the Mozilla version, but it is easily loaded in EDGE How can I open this site with Mozilla? website : https://app.setareyek.ir/

whenever I search something that (is / sounds like) a product amazon links or other online shopping links show up as the number 1 results after a short delay. I have been redirected to amazon many times when I tried to click the #1 result but the amazon link pops up where the #1 result was.I have uplaoded 2 images the one where steam is the #1 result is what i want it to be, the second Image is what happens after a short delay.

My images look all glitched out and scrambled. It wasn't like this before, and I don't remember if I changed anything in my about:config.

I use Last Pass for passwords & it's worked in the past on Firefox. After updating Firefox, the Last Pass extension in by toolbar is black - in the past I would click that, open the Last Pass page to sign in, then the icon turns red and functions. Now when I click the icon a frozen page comes up that never loads. I can sign in to the Last Pass webpage, but that doesn't turn on the extension.

Any advice appreciated - thanks!

A routine update from Firefox version 99 to version 100 caused Firefox to quit loading web pages, including the Settings page. Firefox appears to load normally but will not display any web page. The only thing that works consistently is Help/About Firefox. System: Lenovo E495 (AMD Ryzen 5 3500U) running Windows 10 Pro 21H2, build 19044.1706 Symptoms:

• Version 100 and higher work correctly in trouble-shooting (safe) mode
• Refresh does not resolve the problem
• Manually removing extensions (NoScript and Cookie AutoDelete) does not resolve the problem
• Uninstalling Firefox and existing profiles (all Mozilla folders in AppData/*), then making a clean install of version 100 does not resolve the problem
• Removing version 100 and reinstalling version 99.0.1 restores normal operation (repeatable with higher versions)
• Updating from version 99.0.1 to version 100.0.2 or version 101.0 does not resolve the problem
• I have not tried removing any Mozilla registry keys

Couple days ago Yahoo Mail stopped downloading attachments of any type. Only happens when using Mozilla. Yahoo mail works fine with edge and android. The following had no affect: (1) signing out and in to yahoo mail. (2) Clearing cache etc in Mozilla (3) rolling back recent windows updates. Occurs with all types of attachments, so not an app issue. Appreciate your help, please include only those suggestions which consider the "suddenly" part...
