Firefox Community Forum

My Apple desktop crashes frequently in different applications (while in gmail, on Facebook, etc.) and it sends a report to Apple every time. It never does it if I use Safari. If I can reload Firefox to fix it please let me know how to do that. Thanks.

Firefox 157.0 (aarch64) macOS Tahoe 26.7.1

When I click on the link to a PDF to open it in Firefox and click on the Save icon in the file viewing UI (see attached image pdf-save-icon.png) to save it to my local device, no File Save dialog box opens and nothing happens.

If I right click on the link to the file instead of opening the file, the file is saved silently to the Downloads folder with a name that ends in .pdf.part (see attached image filename.png). That typically indicates a partial, failed download, but in this case, if I remove the .part from the filename, the result is a viable PDF.

Hello, apparently with the newest update to Firefox, they decided to change locations for elements like the sidebar and extension icons and the forward and back arrows. Is there any way to change these back to their previous locations (e.g., forward/back arrows on left side of search bar)? Also, I appear to be missing the icons for refreshing a page and opening a downloaded document. Where can I find these and how do I add them back to my header bars? I didn't find anything under the Settings menu.

Any help appreciated, as these apparently tiny changes are driving me crazy. I especially miss the refresh and open download buttons.

Thank you!

Hi,

I'm autistic and I find the new design updates really, really disturbing and I need to change it back to the old design.

I read on the help article for reverting to older versions that it'd be better to ask if there's a workaround instead of downgrading because of the security issues, so yeah does anyone know how to revert to the previous Firefox design and maintain the current version of the browser?

By the new design, I mean the roundness of everything and the teardrop shapes for whatever's left.

I'm still gonna revert back for now but hopefully there's a fix I can use.

I just upgraded Firefox to version 156.0.2.

It no longer plays mp4 content from a website. It says "No video with supported format and mime type found".

This used to be OK.

I just updated to Firefox Version 157.0 and set up vertical tabs on the left side and love it. I also have "Hide tabs and sidebar" clicked which I assumed would hike the sidebar until I moved my cursor to the left. That doesn't happen. The icons for the various tabs remain displayed. Am I wrong to assume that this setting means the sidebar will be hidden until the cursor is moved to this area?

Thanks for your input.

I cannot seem to revert the changes done to the Firefox User Interface completely. I have set browser.nova.enabled to false, which reverted some changes, but the address bar and the bar of which the websites are (which I do not know the technical name of) are still "squished". Is there a way to fix this? Thank you for your time, -Sargent Venipede

The new, awkwardly rounded tabs are just awful, and on top of that, you can’t change them anymore. Please bring back the old MINIMALISTIC and STRAIGHTFORWARD look of the tabs, I’m begging you. I used Firefox only because of its minimalist style. Why are they forcing this incomprehensible THING on me without the option to choose the visual style myself?(((

When i updated my browser today it showed me a page which said that VPN can be used by clicking on the VPN button in toolbar so i tried to do it but it is not showing in my browser and also it is showing nothing related to VPN in settings.

Exported my Firefox bookmarks from my HP DESKTOP to a flash drive and now need to import them to a new Dell laptop. Installed Firefox on my Laptop and it had a statement that stated import bookmarks. Tried it but didn't work. Both systems are Windows 11. was not logged into Mozilla when it was performed. Plan to use Dell laptop as backup to my desktop computer.

COPIED FIREFOX BOOKMARKS FROM MY HP COMPUTER TO MY DELL LAPTOP BY COPING THE HTML FILE OF BOOKMARKS TO MY DELL LAPTOP DESKTOP SCREEN AND IMPORTED THEM FROM THE DELL LAPTOP DESKTOP AS ADVISED. STILL DID NOT GET ANYTHING COPIED TO THE NEW FIREFOX INSTALLATION EVEN THOUGH IT STATED IT HAD COPIED 827 BOOKMARKS. NOTICED THAT THE FIREFOX SOFTWARE INSTALLED ON MY HP COMPUTER STATED THAT IT WAS WINDOWS 10 INSTALLATION. ORIGINALLY THE HP WAS WINDOWS 10 BUT UPGRADED IT WITH FREE MICROSOFT WINDOWS 11 BUT DID NOT UNINSTALL FIREFOX FROM IT AND REINSTALL FIREFOX AFTER THAT. THEREFORE THE FIREFOX BOOKMARKS ARE FOR A WINDOWS 10 INSTALL ON THE HP COMPUTER AND TECHNICALLY NOT A WINDOWS 11 EVEN THOUGH THE WINDOWS OS HAD BEEN UPGRADED TO WINDOWS 11. SO, I GUESS TO PERFORM THE ACTION I STATED ABOVE TO UNINSTALL FIREFOX ON THE HP COMPUTER AND REINSTALL IT ON THE HP COMPUTER IT IN ORDER TO GET IT TO WINDOWS 11 FOR BOOKMARKS? HOPEFULLY I WON'T LOSE THOSE FIREFOX BOOKMARKS?

After my browser automatically updated to 157.0, when attempting to download files on MacOS 27 (Golden Gate) the download window does not populate but a .part file appears in the default download location.

Which dictionary are we using? (Or are we allowing English spelling to be supplanted with American or other spelling?)

Whereas in MS Windows I can choose UK English or one of the many different forms of English in use elsewhere, I'm noting that in Mozilla/Firefox I get the typical warning under a spelling that does not equate with the spelling used in the current dictionary and yet these spellings are not UK English...

Even I choose UK English as my default dictionary the spelling of "colour", "neighbour", aluminium, still give this indicator.

I was using the "read aloud" function in chat gpt window today and suddenly it started showing me an error message "Unable to read aloud" . It did not affect Chrome. I used many of the troubleshooting recommendations but none worked. troubleshoot mode failed to fix it. private window did not fix it. default change for audio and video did not fix it.
