Ondersteuningsforum voor Firefox

I have an urgent problem. I am about to loose access to my existing primary and secondary emails, as i have been forced to try to change to a new email provider. I set up with Gmail and it was working fine until I updated windows on the 20th. Now I cannot log in I get the following error massage:

Corrupted Content Error The site at https://mail.google.com/mail/u/0/?pli=1 has experienced a network protocol violation that cannot be repaired. The page you are trying to view cannot be shown because an error in the data transmission was detected. Please contact the website owners to inform them of this problem.

I have searched online and deleted my google cookies and cleared my cache without effect. I am getting desperate to get this fixed. My new ISP does not provide email addresses but I need two of them one for myself and one for my mother. I have been told that my existing emails my be deleted as early as 30th March 2021. I have been trying to get these new emails in place for nearly three months and I feel like this is the last straw.

I know I am using an old version of Firefox, but I need to keep my old style extensions as I use them to help me with my visual disability.

Yours Desperately, Kaelkitty

Hi! I am running a wordpress cms based website please help me in fixing design of this as its not user friendly for mozilla users.

How can we clear / delete our data from Firefox installed on a device we don't use any more remotely. Just by removing the device from Firefox account will not clear the login and password information from the browser in the old device.

hi, whoever reads this. I've noticed a problem recently in some websites where certain elements (e.g. logos and icons) completely disappear and get replaced by strings of text, which I'm assuming is the code that is used to create them. Usually, it's just one icon, typically a search or menu icon, but there have been more drastic cases, such as the screenshot of the Encyclopaedia Britannica website that I attached. Notice that many buttons, while still functional, are covered with strange text. One thing I'm suspecting is that I intentionally or inadvertently disabled an element (or something of that sort, sorry for my ignorance in the specificities) ages ago that was supposed to make these work, but I don't remember what I disabled, if I ever did. But other than that, I have no clue what causes this. In Tor, where I don't have an account and never interfered with the setup or settings, everything seems to work just fine; the buttons are right there. Hope someone can be of help.

Hello,

When I go full screen mode on firefox (version: 87.0 64 bit) and mac (version: Big Sur 11.2.3) both the top and bottom apple tool bars go away (which I want to happen) but the firefox search bar and bookmarks are still there on top.

When I go FS on my windows computer, the full web page displays and then when I hover op top the firefox search bar pops down until I hover off it, this is what I want to happen on my mac!

See attachment of firefox search bar staying while in FS mode and please help! Thank you for your time.

Yesterday this issue arose where when I would run Firefox it would open then close within a second. I've tried reinstalling and the same issue arose. I can't seen to start it in safe mode or change profiles. Is there any advice for this?

Hello to all.

By mistake I have cleared the browsing history, cache and cookies. I would like to recover the old precedents for "browsing history" because it is now completely empty and stores the list of visited sites.

I am using mozila firefox in my lenovo laptop. everything is working fine on mozilla firefox but it shows layout issue, home image stretching a lot on a website for which I am working for my client. here the website <a href="https://bestsportsmask.com/">https://bestsportsmask.com</a>

I have used sync for long on several devices and different operating systems (Win 7, Win 10, IOS) in parallel. Most interesting and useful is for me synchronisation of the toolbars with Bookmarks. It worked fine up to today. Today I opened Firefox and found my bookmarks as they were about two years ago. Oops... so I tried to synchronize but failed. No changes were applied to my bookmarks. I assume, my bookmarks are also being stored on several other devices I used for Firefox. However the newest sinchronization on the mozilla server does not contain the accurate valuable data. How can I manage to save sync data from a destinct device to the sync server and determine that as the current data set to be valid for synchronization with all my other devices? In other words: set the direction for synchronization. I did not find this option on my current (82.0.3 (64-Bit)) installation. Could anybody help me? Thanks Juergen

See attached picture. Am I right to assume the (Q) next "Inspect Element" is a shortcut key? If yes, how does this work? pressing the Q-key on my keyboard does nothing. Please clarify.

Today, when I enter any search term, Firefox puts up a new page saying there is "excessive network traffic" from my computer. The search is for anything, such as "Firefox contact" or "grow azalea". Is this a feature in a new Firefox update?

Windows 10, 64 bit. Firefox ver 87 For the past several days I have not been able to sign into my online banking at Scotiabank. When I enter my user name and password I immediately get an error message "Sorry, we couldn't complete your request". At the top it says "something went wrong" and the message comes from the Scotiabank site saying "generic-error". I've tried refreshing Firefox, removing all cache and cookies. Have tried restarting the computer. I note that Firefox appears to have updated itself on April 3rd and that appears to be when the problem started...could be just coincidental. Other web sites appear fine. I can use Microsoft Edge to log in to Scotiabank just fine as well, but I prefer Firefox. Anyone have thoughts on this? Thanks

I updated to the current version, and ever since then, The Weather Channel website will not load and every time goes to OOPS! Cannot Find Page. Every single time, but in other browsers it loads just fine. Any thoughts?
