Firefox Support Forum

Hello,

I just upgraded to Firefox 87 and noticed that I wasn't able to go back to the previous webpage by clicking on the backspace button like what I have done in the past if I'm not using a mouse on my laptop and had to click on the back button in the toolbar with the trackpad. I'm not too sure of why that happened with the upgrade and was a little surprised about that. Hope I can be able to get around this in some way if one of you know anything about this. Thanks.

This morning I closed my bookmarks sidebar to frame open windows better. Now there is no option to restore it. Help please, as this is my best organization for web browsing. Thank you!

While playing one of those free poker games there seems to be excessive RAM memory usage. Nothing else running which can account for it. Also, it shows several Firefox processes while, again, there's only one tab open.

The reason I noticed is that the game which usually runs smoothly began to be choppy/jerky, so I opened Task Manager to have a look. Note: Didn't investigate internet connection speed.

Why is Firefox using so much memory and slowing things down?

I think the title covers it. Until recently, pressing the <Backspace> key on the keyboard would take me back to the previous webpage. Now it doesn't.

Using FF v87 in Win10 Home.

Is there a way to set a web site as my home page and not have to reset it every week or so? Also, when will we be able to choose what web site is loaded when we open a new tab?

My ISP is Plusnet. When I try to access their website using Firefox browser I get the following error:

=====

Secure Connection Failed

An error occurred during a connection to webmail.plus.net. Cannot communicate securely with peer: no common encryption algorithm(s).

Error code: SSL_ERROR_NO_CYPHER_OVERLAP

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the web site owners to inform them of this problem.

I have reported the problem to Plusnet but they say 'not our problem'. Their reason being that the problem does not occur using Google Chrome.

Can you help please?

I have used/accessed Google Maps for years - so many I can't remember and now today I get this message

We are sorry, but you do not have access to Google Maps. Please contact your Organization Administrator for access.

Is this a FireFox muck up or what?

I have recently switched from Chrome to Firefox. All features that I used in Chrome seem to exist in Firefox as well, until I found out that there are no local overrides in Firefox?

Some Information about this feature(it firstly appeared in Chrome's dev build in 2017): Local Overrides

Personally I found this feature very useful and convenient when debugging directly in your browser and immediately takes effect after a page refresh.

I wonder if anyone else submitted a feedback or even had a discussion about this feature? I tried to send a suggestion about this feature but they temporarily disabled the submission form.

Hi all

For a while now I've had a problem in Firefox where images randomly show up with green blocky glitches or yellow lines on them. Also sometimes text does not show correctly. I've attached a couple of examples. The image is from my Facebook feed (but it can happen on any website it seems) and the text is open tabs - the one on the right is this page.

Any suggestions? I've refreshed the Firefox install, and have only one add-on - an ad blocker. I've tried two different ad-blocking add-ons and the problem persists with both.

Thanks

Recently Windows forced an update to 20H2. All my other programs display font okay. However Firefox (desktop -- latest version) does not display fonts properly. The letters flash between thin and normal.

Strangely enough when I took a screen shot to demonstrate the weird font display the fonts were perfectly fine in the screen shot.

I took a picture with my phone. In the image one can see difference in the width of the two L in "all" As mentioned this is only happening in Firefox.

Thanks for any clues.

Hi,

I had to delete all my profiles and completely reinstall Firefox because Firefox was not changing the color of previous websites to purple no matter what I tried. I thought I could delete the profiles and create a brand new one to start over fresh.

After reinstalling Firefox (latest version) I have run into a problem where under <about:addons> <Plugins> it shows a yellow box and an error saying "Widevine Content Decryption Module provided by Google Inc. will be installed shortly".

This message won't go away and Widevine will not be installed at all. I cannot browse and Netflix, Hulu, HBO Max etc.

I have tried unchecking and checking the <Play DRM-controlled content> under <about:preferences> which does not work.

I have also tried going to this (link)link and manually installing it but the webpage for my OS's .zip file won't load for me.

Hi there,

We use GMail/ Calendar/ Drive for our business. On the official account, I am seeing a continuous - multi-day - situation where my Google Drive won't load when I point my browser to it unless I do at least one refresh after getting to Drive and waiting for my list of folders and documents to show up.

In the mean time, the following error shows upon on the bottom left of my screen - "The server encountered an error. Please try again later." - this has persisted for over 2 weeks when I restarted using Fiefox earlier this month. I do not get this error when using Chrome or Safari.

Today, I am also not able to see the user who last modified a document or a folder last, as you can see in the image below.

Please tell me what I can do to fix this issue.

Thanks, Mahesh

Hi, I'm using ASNA Wings AS400 Web app. Ctrl-V shortcut does not work.

I observe this error from the controller.

I don't have a problem in other browsers.

Dynamic site content binance.com doesn't work after updating firefox. You have to constantly update the page. Please how to fix it?

Every 20 minutes or so I get a notification from Bitdefender Online Threat Prevention module indicated it has blocked a suspicious connection. This has only started about 2-3 days ago. The only information the popup indicates is:

"firefox.exe attempted to establish a connection relying on an unmatching security certificate to gitcdn.xyz. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one."

I performed a full system scan and found nothing harmful. Anyone know what this is or how I can fix it?

I'm trying to import my saved logins and passwords from Chrome to Firefox. When to try to do this I get prompted to create a Primary Password. Whenever I try to do this, I get a message saying, "Unable to set Primary Password." I also can't cancel out of this or switch to another tab--I have to ctrl-alt-del and close Firefox to get out of it. I also can't create a Primary Password through the options menu. Anytime I try to set a primary password it just says "Unable to change Primary Password."
