Firefox for iOS Support Forum

I'm getting bad request error messages when I try to sign into Firefox on my iphone. I would like to sync my iphone browser to my Macbook. Right now I'm not able to sync bookmarks or any customization.

i have searched for hours on how to share a webpage (in firefox broswer) i am viewing on my iphone 15 to my macbook firefox browser when it is open.

i have had no success

Hello, I get the 500 Error screen when trying to sync Firefox on my phone. When trying both scan or email. ( I had to erase the app after having signed out, to try and fix a bug. The app kept freezing) Can't seem to find any help from Firefox's... elaborated support system. I'm probably dumb. But I don't have any more time for that. And I can't speak with anyone anywhere apparently.

Waiting for a potential answer here, or switching back to Safari in 24h.

Thank you !

I don't know if syncing's the problem. My business email is locked. I haven't been able to use it and it is critical that I have this working. Can I chat with someone?

I realise both the device and firefox 8.3 (5826) are end of life. Just defaulted this old tablet and wanting to setup sync again., it scans the QR code but no more.

Is there any manual / otherway of getting sync on it at all ?

Thanks in advance, no bother if no

I download the APP, but whenever I use it and try to do anything with it, like sync with another device, it tells me I need to download and use the app - EVEN THOUGH I AM USING THE APP!

Hi,

I have Firefox on my desktop, laptop and iPhone. The only device on which I do not have access to my usernames and passwords to login into my online accounts is on my iPhone. And yes I have set it up correctly with the QR code etc... By reading all the messages from other users, I'd like to know if I need to ditch Firefox for good and go back to chrome. Or will someone fro Firefox come up with the fix for that glitch. Waiting for a couple days. After that, Firefox will be history for me. And oh yes, I will talk about this every chance I get while on TV.

I checked community and tried every single suggestion like; I did disconnect all devices and reconnected desktop version first and then synced with my iOS one, didn't work for me.

I just installed (and reinstalled) Firefox on my iPhone 12 Mini, in the hopes that I could sync bookmarks, etc., that I have set up on my notebook's Firefox browser. I have gone through all the steps (twice) and it still will not migrate my bookmarks to the ios version. My account shows that Firefox is active on both devices. What am I missing? John

Tried syncing Firefox Windows 11 (version 21H2) with Firefox mobile browser (Firefox 105.0) and get the following message: 500 Error Oh dear, something went wrong there. We've been notified and will get working on a fix. I have a iPhone 12 Pro. iOS Version: 16.0.2

Neither using the QR code option or the email option work. Both result in a white screen.

By using the iPhone's camera to scan the QR code (instead of using Firefox) I can see that the QR code is point to https://mzl.la/MYCODE. This URL in turn is redirecting to https://app.adjust.com/somecode?campaign=firefox-desktop&adgroup=firefoxview&creative=CODE-123. Opening this URL in Safari gives me a white page with a "Download App" button to download Firefox (which I already have installed).

My Firefox account has the setting "Allow ⁨Firefox Accounts⁩ to send technical and interaction data to ⁨Mozilla⁩." set to off. So probably none of this tracking should occur.

In any case, I went to Firefox settings and turned on "Allow Cross-Website Tracking". I also went to Safari settings and turned off "Prevent Cross-Site Tracking", "Privacy Preserving Ad Measurement" and turned "Content Blockers".

Then I tried syncing again. The result was the same white page as before.

Dear Mozilla Team,

during the recent weeks I was away from my main PC and primarily used my iphone to browse the web. Every now and then I sent a link to the PC using Safari's share and the integrated send to function of Firefox for iOS. This usually worked really well, even when my PC was powered off. When I got back home and started my PC, sync would take forever, but was then interupted and all further tries to sync (hoping to get those tabs eventually) failed.

My question is if there is a log file of all those links that are sent to different devices? I believe there has to be one given that Mozilla's servers are being used and tabs (usually) arrive on powered-off devices following a request to the server.

If there is, please tell me how to access it/send it to me. If there is not, please take this as a feature request (a sent links history being gathered locally as part of the wider Firefox profile maybe and as a viewable list of all shared tabs for all devices so that tabs can still be sent to single devices but also accessed from others, similar to how tabs can be accessed from all synced devices).
