Diễn đàn hỗ trợ Firefox

I am getting an access denied message with shop.coop.co.uk, but not with any other online shopping site.

I have tried all the usual suggestions like reboot, clear cache, remove proxy, and I do not have VPN.

I have downloaded the html of the message, and taken a screenshot of it as shown below. Looking into the html, there are references to Incapsula, which may suggest where the problem lies?

This problem started when I had to change my Virgin Media hub from Super Hub 2 to Hub 4 around July last year.

One suggestion that is often made is to delete cookies. However it is not clear which cookies may be relevant.

Any ideas on how to identify the source of this issue will be most welcome.

This is the 3rd time I have had to post this. I am getting very frustrated. I DO NOT want the search engine within my address bar. Nothing anyone from you "community" helped to disable the search engine in my address bar. Opera, Edge, Chrome, the user can disable the search engine in the address bar. Why is Firefox so different? And difficult?

Recently, Firefox updated and ask me to setup a profile, which I have not yet done since importing my data from google chrome in 2025. After skipping the setup, Firefox then deleted all my data and it has since been irecoverable. I have already checked the box last update that specifically said to not ask me again for setting up my profile. After the recent update, the question popped up again and now I cannot recover my original profile, all my browsing history, all my browser-saved data, and all my cookies and logins

We are a high school alumni association and Firefox is used primarily for our social media sites but yesterday it started not opening our Facebook page properly - doesn't open the whole page, won't open the comments and if you click on something it just sits and spins

Good Morning, I have been trying to access Whatsapp web through the Mozilla browser but i have been unable now for the last four weeks. When i use other browsers then i am able to access the internet. Thank you.

Hello,

I have my browser startup settings set to 'open previous windows and tabs' However, every time I start up firefox, it is on the default new window screen rather than my previous tabs. This feels frustrating as I have to reopen the tabs every time.

Would it be possible to fix this?

Thank you.

I am unable to follow instructions for activating Backup in Firefox. I don't even have a Manage Backup button. What I have in its place is:

Backup

Restore your data Use a Firefox backup file from another device to restore your data.

Choose backup file...

This is a brand new problem, for me. It just started today when using FireFox. On nearly all websites, including Mozilla support, when I click on an embedded link on a site, firefox asks me to select an app to open the https. Even if I tell it to let firefox open all https, it still asks me everytime. to make it better, it still doesn't always let me open the link and I go through the same thing when I click the link again.

This also happens when clicking on the search box in *any* search engine, e.g. Google, Startpage

See the image below.

I've attempted to change all cookie & tracking settings, no help. I even uninstalled and reinstalled Firefox.

This is making FireFox useless.

I had to use my default browser, Brave, just to submit this question. I only use FireFox for social media accounts, sites I need to link to my sm accounts and the occasional web search. For example, linking my Etsy shop to facebook. When I clicked the link "link to facebook" is when I noticed this problem.

I am trying to create a backup of FireFox for moving from a Windows 10 machine to a new Windows 11 machine. The instructions for creating a backup don't make any sense.

--- Click the main menu, and go to Settings. Select Sync. Scroll down to Backup, and click Manage backup. Choose the location to save the backup file. ---

When I click the Main Menu, go to Settings, Select Sync, there is no Backup listed. If I search for the term "Backup", this is the result: "Sorry! There are no results in Settings for “backup”. Need help? Visit Firefox Support".

Syncing is on, so I am assuming that FireFox is being backup?? Or am I missing something somewhere?

How can I remove the moving blue ball from the tab of a frequently used website? It's distracting and hopefully not symptomatic of a problem It appeared on this new computer/monitor, used to be an icon Thanks, --Laurie
