I’m using Firefox on an Android tablet in PC mode, paired with a keyboard and mouse. To enhance the desktop experience, I’ve switched the tab view from grid to list. However, I can’t enable full-screen mode for the entire app, something I can do on Firefox Desktop. On YouTube, videos automatically switch to full screen when I enter full-screen mode, but this feature seems missing for the browser itself. Maybe the full-screen option isn’t available in the settings.

Recently transferred from Chrome. My understanding was Firefox private browsing was supposed to work similarly to chrome incognito mode; once you close the browser, all local files are deleted and cookies are cleared.

However, with Firefox it maintains my logins. If I log into an account while private browsing and the close the browser, I’ll still be logged in next time I go to the website even if it’s days later (and I have never logged into this account in a non-private browsing window!)

I never had this issue using chrome incognito, so it seems to be a Firefox problem.

Is this just not something Firefox supports? Is there any way to prevent storage of cookies and private data?

Hello, I appreciate the community and would blike to know if it's possible to receive email or send emails to other addresses within the fire fix account Mozilla account email inbox?

Firefox 136.0.1, Linux 6.8.0-55, have set Okular as default pdf application, however Firefox will not open pdf file when downloaded nor will it open the file when selecting Open File from the Download Icon on the toolbar. Only was I can get to file is to select Show in Folder option and open from within Dolphin.

For years I have used the extension 'Calendar Tweaks' because it colorizes the entire event in the calendar. This extension is no longer compatible with versions of Thunderbird after 74 so I have stop updation after Version 69. However in resolving problems with authorization I needed to update to the current Version of Thunderbird so my events in the calendar now just show the category color at the edge of the box instead of the entire box. Is there a way in Thunderbird to colorize the entire event box or another extension that does this.

When will Gecko-based Firefox Android increase the number of default search engines in 2025?

Currently it hosts only Big Tech namely Google and Microsoft Bing and DuckDuckGo, which is Bing and MSN results in DuckDuckGo and Qwant (same Bing results) latter which works only in the UK.

I'm using Gecko-based browsers like Fenix and Mull and Iceraven, and they all come with like 5 to 10 search engine options.

Adding new search engines is a mess and doesn't sync with Firefox account settings, so futile efforts.

Even Chrome allows us to select our search engine, if we are visiting it too much.

Is Firefox really privacy based browser or just Big Tech in Firefox like Google as default search engine out of the box, no asking which the XYZ user wants?

I wanted to use the new VPN feature and the icon initially showed up in the top right, but it has disappeared and is not present in "customise toolbar" or privacy settings either.

Installed Firefox on my laptop. Already running on my desktop.

Whenever I try to open a link, I get: Get an app to open this 'microsoft-edge' link

Your PC doesn't have an app that can open this link. Try looking for a compatible app in the Microsoft Store.

Is this Microsofts way of saying "Use Edge?" Can I change settings to make it work?

I am using an iPad. How do you stop firefox from opening a new tab when clicking on a link? I want to it to follow the link in the same tab almost always.

Thanks for you help!

Need help setting up my domain name with godaddy and Thunderbird email client. need to get DNS Records from godaddy also. Having more trouble with this than I should, I think. I have already setup an email account on Thunderbird with earthlink/mindspring and icloud. No problems at all, in fact, both were very simple. But no so much with the domain name and godaddy. Any assistance will be greatly appreciated.

Please tell me what the difference is between "size on disk" and "user quota"? I don't understand why my mailbox is full when all folders take only 1/5 of the available space. My hosting give me 5GB, a user quota in mailbox is 4.7GB (in the app for computer: the main folder containing all other folders - properties folder - Quota - Storage: 4.7GB), size on disk is 853MB (in the app for computer: the main folder containing all other folders - properties folder - General Information - Size on disk: 853MB), and the weight of all folders is ~1040MB (the sum of the weights of all individual folders in the main folder). None of the numbers match. I understand that the sum of the weights of all folders is probably supposed to be 853MB, that the discrepancy is due to rounding the numbers. I understand that some space may be "lost" from the hosting because installation files take up some space, so I actually have 4.7GB to use, not 5GB. However, I don't understand why my mailbox is full, when from 4.7 GB only 853 MB is used?

How to disable home button icon on URL bar in Firefox Android like Chrome allows in 2025?

It takes up too much space and URL is hidden and unreasonable. In Chrome, all is optional and customisable.

Is Firefox team updating it to current standards of 2024-25?

I am using Firefox nightly on Android. About two weeks ago I noticed that my toolbar got moved to the bottom after some update, while address bar is still at the top. I tried looking for it in settings but couldn't find anything about toolbar, that's weird since I was able to customize it a few years ago when I installed Firefox for the first time. So I looked it up on the internet and they say that it's in Settings/Customize/Toolbar, but in my browser settings instead of Toolbar there is Address bar settings. Has toolbar's settings been moved somewhere else? It looks like in previous versions it was under Customize section.

I am using Thunderbird 115.5.2 (64-bit) on an older iMac on OS 10.12. I have four email address accounts, all gmail, and using POP. I have stored emails I wanted to keep in sub folders in Local Folders. This has all worked well for years.

Yesterday I lost lost all content from some of the subfolders in Local Folders, while some retained some content and a few seem intact. I also lost most emails that had arrived in the inboxes in the last week. The folder pane still shows the accounts, with their own set of folders. As usual, the inbox folders are highlighted with the number of new emails downloaded from the Gmail server to each address, but I can not see them in the message pane, or find them anywhere else. I sent a test message from one of my addresses to another – It didn't show as sent in Thunderbird, but did go through the gmail server and the message count of downloaded messages on the recipient address went up by one, but I couldn't see the email. Then I tried clicking on the folder "properties" then 'Repair Folder' but nothing happened, although the information on that window showed the number of messages and MB that I would expect to be in that folder, rather than what was there, which presumably means they may still be in there somewhere? I would be very grateful for help – I'm not tech savvy and feeling completely lost.
