Firefox supportforum

I've used FF for years and always had - "Open links in tabs instead of new windows" and "When you open a link, image or media in a new tab, switch to it immediately."

Until very recently this worked well.... now there are two identical tabs opening the link and the switch to immediately does not work.

I am having trouble sending tabs from my phone to my PC. My device is connected to my computer, and I can send tabs from my PC to my phone successfully, but not the other way around. I have no idea what could even be the issue, and I have only seen people asking about sending tabs from PC to Mobile, not the other way around. Is there something I am missing? None of the Firefox troubleshoot pages have helped.

For the last few days the ebay website is very slow when I open it. If I switch to Chrome, ebay's website loads okay. All other websites seem to load through Firefox with no problem. Any ideas???

The box in Settings > General > Startup > Open previous windows and tabs is still unticked.

Does anyone know what could be causing it and how to fix it?

Thanks :)

I've seen other people ask this question, and the stock answer appears to be: a) They may be different subdomains, but they're the same site. b) Just add an extra bit on the end of each user name so you can get at the correct one.

Unfortunately...

a) No they are most definitely not the same site: myFirstClientsDevSite.mytestdomain.com mySecondClientsDevSite.mytestdomain.com myThirdClientsDevSite.mytestdomain.com myFirstClientsUATSite.mytestdomain.com mySecondClientsUATSite.mytestdomain.com myThirdClientsUATSite.mytestdomain.com

You see the problem? Firefox treats all those sites as being "the same site", even though they patently are not.

b) I'm working with a lot more than three clients. Plus, that suggestion is basically "we admit that our product is broken, here's a work-around that a few people may be able to use".

And finally: I'm pretty sure that Firefox used to be able to discriminate between subdomains, so the question isn't so much "how can I get it to work", as "why was it taken away in the first place".

I accidentally hid the menu bar and toolbars (with an accidental keyboard shortcut, I think), and when I re-enabled them, now the tab bar is above the location bar instead of right above the content windows. How do I move it back? I can't find the "browser.tabs.onTop" setting in about:config, or any check box in the View menu, settings, etc.

I'm using Firefox 119.0.1 on Ubuntu Linux.

Thanks!

Hello, when initiating a request for conditional mediation with webauthn I get the following error:

TypeError: 'conditional' (value of mediation) is not a valid value for enumeration CredentialMediationRequirement.

However when asking whether it's available with `await window.PublicKeyCredential.isConditionalMediationAvailable()` it does return true. Is this a bug?

I use Google search via Outlook. Lately every time I do a search I have to use a captcha. This is frustrating and how do I delete this step when searching a subject?

Hello, once every morning I start 14 tabbed Internet pages. The pages do not fully render unless they are in focus. Is there an About:Config or other setting where I can get all 14 pages to fully and completely render without getting each one into focus one by one?

This is a very slow process and is annoying over time. I believe there was a time where Firefox would render all tabs/pages without getting each one into focus.

Thanks in Advance.

Since the last update (earlier this week) firefox uses large amounts of memory. It shows in the windows task manager 20 and more instances of firefox being open and one of them using 85%-90% of the available memory. I looked up help articles regarding this issue and one of them mentioned to "Delete content-prefs.sqlite file". When I do that it will help for a short period of time but then the issue is happening again. I'm using Windows 11 64 bit.

I'd appreciate some advice on how to deal with this.

Just pointing out the idiocy of this software... despite having tabs with multiple pages of the same host website open, Muppet-Zilla FireFux starts giving me the old Secure Connection Failed rubbish. Take the link, open it in public of MFF, it opens fine. Even a page that was open fine, try to open a link it, Secure Connection Failed rubbish. Hit the back key, A PAGE THAT WAS OPENED, then Secure Connection Failed rubbish. Yet in CCLeaner, Vivaldi, Chrome, Edge, no issues. So, I guess the message in that is clear - uninstall MFF, never install again. Good to know.

I was using Lightspeed today, and the website pops up a confirmation dialog box (probably through JavaScript) so that you can confirm that you want to do a specific action. I got annoyed with the dialog and clicked the included "Don't allow this website to show prompts anymore" box when I hit OK. But now it won't perform any action that requires you to hit the OK in the prompt, so I need to make the dialogs come back so I can do my job. I can't find any setting anywhere in the browser that I have actually disabled or changed by hitting the box in that prompt.

In the Microsoft Store there are all these updates for video extensions like "AV1 Video Extension". Should I be doing these updates? Do they make any difference to streaming video on the Firefox Browser?
