Diễn đàn hỗ trợ Firefox

I have two installations of Firefox on a desktop and a laptop. The first installation is pinned to the Windows toolbar and the 2nd installation has a shortcut pinned to Windows Start.

When I saw that the latest update of Firefox to 154 allowed changing icons, I changed the 2nd installation to a different Firefox icon (mini-fox with black background) so it was easy to see which installation to use when both were open.

The problem is the changed icon for the shortcut is wrong after shutting down the computers. I do not recall having this problem with the 1st installation or on my 2nd laptop where I only have one installation of Firefox.

I suspect this is just a glitch that will likely be fixed in a future update, but it is annoying to have to go through the process of changing the icon every time I startup a computer. If anyone has found a solution for this, I would very much appreciate your help.

why did firefox delete most of my shortcuts on my old pc after i synced with my new laptop and how do i get them back. I am a senior of 71 yrs not a computer tech.this just screwed everything up for me!HELP!!

Hello everyone

When I open a session on MacOs I have full access to Firefox and Passwrods. That is not a protection good enough for me How can I stop this ? Should I disconnect from Firefox before closing the Mac Session ?

Thank you in advance

On Firefox I have repeatedly pinned four tabs for websites that I use frequently. The pinned tabs disappear at unpredictable times, not necessarily when I re-open Firefox.

I didn't know I need to keep a device on if I want to sync my old data. I read it thoroughly. This is annoying, I don't want to lose my Sync data from this because I didn't know. How do you guys retain your Sync data if I were to reset my password? My computer just got fixed and I don't like this greeting of where all my data like history and bookmarks flushed down because I wasn't signed-in in a device nor did I place a key or something.

Good Day.

I have encountered a problem recently with on particular forum site.

When I attempt to login I receive an error after pressing the submit button. 

The form displays this error "The submitted form was invalid. Try submitting again."

I have been using the site regulary for several years and have never had this problem

The following is what I am using:

    Firefox ver 153.0.1 64 bit
    Windows 10 and/or Windows 10 (yes this is happening on all 3 of my PCs)

The forum site is using phpBB Forum Software. I do not know the version. As stated above they have been using this software for several years.

In trouble shooting this issue I have discovered that if I do the following in the specified order I can login and create and respond to posts and Private Messages. But as soon as I log out I receive the invalid form message until I do the following steps again.

            1) Clear all cookies, temporary cache, site settings, browsing and download history, site settings
               and saved form info.
            2) Shutdown Firefox 
            3) Navigate to my profile with Windows Explorer 
            4) Delete the file cookies.sqlite

I must do this each and every time I access the site.

I am at a loss as to what to do about this. Does Firefox have any error logs or console logs? If so how can I enable them to see if I can get a better idea of what is happening?

Thanks in advance for any help with this.

Hi,

last year I deleted my paypal account. Before that I deleted all entries and connections to abonnements in paypal. A few days ago i received an e-mail from Mozilla that I should pay my VPN abonnement. I would like to do so, but after logging in, I was shown an error message: "Invalid payment information. There is a problem with your account. Manage payment method."

When I go to "Manage payment methods," no options for other payment methods appear, only a PayPal link. What should I do now?

Thank you for your help!

latest update seems to have broken firefox 155.0.1. It opens but then becomes unresponsive. Two different PC, both win 10. How can I revert to previous?

I can not get extra info from troubleshooting page cause FF won't open so as to be used.

Current firefox version: 155.0

Since the last few updates, update frequency of title bar of inactive tabs slows down over time. Sometimes there is important info in title bar that should be updated frequently. Are there any flags in about:config that can be reverted to achieve that?

Since last week there is a cookie that I can not remove in the Manage cookies and website data panel. It is called about.ef2a7dd5-93bc-417f-a698-142... There is probably more but that is not shown in my view. How can I remove that?

I have Firefox 15.3.0.1 on two computers. One one, when I go to about:config, there is a search bar with an option to "Show only modified preferences." On the other computer this search bar is missing. How can I make it display on the second computer?
