See the attached screenshot. There is NO "Add Split View".

Hello, I have an issue with installing other extensions. Every time I have been trying lately it keeps prompting me to check my internet connection. I have checked it, it is fine, going strong, supporting constant gaming with no lags or spikes, I have no VPN active when trying to install. Are extensions no longer supported by newest mozilla version or something? It is the only browser with this issue and I will switch the main browser if I cannot get extensions to make life easier.

On the newest firefox update on Windows PC My PDF reading has been not displaying PDFs correctly on Firefox I tested on other PDF views and they work as normal (All images are normally white with black text PDFs) Sometimes it displays nothing at all (as seen in Image 1) Some pages will display correctly but the rest won't (as seen in Image 2) Some pages will display text but strangely (as seen in Image 3) It does flash white sometimes while scrolling but it still doesn't show text

I got tired of the shenanigans with the latest "upgrades" to firefox (132 & 133) so I rolled back to the last working version (131.02). In doing so, it required me to create a new profile, which I did. Doing so WIPED OUT ALL OF MY BOOKMARKS, SETTINGS, ADD-ONS, OPTIONS, HISTORY, EVERYTHING!!! I now have a blank version of firefox.
How in the world can I get them back???
PLEASE HELP!!!!

I know that typically mozilla does not put a low bound on advisories, and https://www.mozilla.org/en-US/security/advisories/mfsa2024-40/ is the advisory for vulnerabilities fixed in ESR 128.2. CVE-2024-8387 is listed here. yet the advisory for 115, https://www.mozilla.org/en-US/security/advisories/mfsa2024-41/ does not list this vulnerability. Was this something that was only impacting 128 (for the ESR builds) or is there a mistake that either 115.15 did patch it but it wasn't documented, or the patch has been missed and ESR 115 is still vulnerable?

I looked at the system requirements page at https://www.mozilla.org/en-US/firefox/141.0/system-requirements/ . For Windows devices, the operating systems supported are listed as "Windows 10 or later".
In October 2025, Microsoft officially stops providing feature and security updates for Windows 10. However, they offer consumers and businesses the option of enrolling in 1-year, 2-year, and 3-year subscriptions for Windows 10 devices which will provide another 1-year, 2-years, and 3-years of additional security updates. You can read more about this at https://learn.microsoft.com/en-us/windows/whats-new/extended-security-updates
For those individuals and businesses who will be enrolling devices into the Windows 10 ESU program, will Mozilla continue to support Firefox on Windows 10 after October 2025, at least for those receiving security updates through Microsoft subscriptions? Or at that point will Mozilla consider Windows 11 to be the only supported Windows operating system?
Thank you!

Running Firefox on macOS Sequoia 15.0. Afternoon of Tuesday, 8 October, Firefox abruptly ceased loading any pages. I eventually learned of the malware incident and downloaded Firefox 131.0.2 last night and overwrote the existing file. It worked for a brief moment, then also ceased functioning. Have downloaded 131.0.2 several times now, with no further success. Currently dead in the water with Firefox, and stuck with Safari. :(
An extension I use must be incompatible or something

We are in an enterprise environment and for years we have had disabled automatic updates.
Firefox ESR 128.2.0 has been deployed with defaults and these settings have been configured to override previous settings.
Computer Configuration > Administrative Templates > Mozilla > Firefox
- Custom Update URL = Disabled - Disable Update = Disable - Application Autoupdate = Enabled - Background updater = Enabled
We also have a system proxy configured.
Updates do work if someone goes to Help > About Firefox.
Looks like the update interval is once every 7 hours but how is this triggered?

After an update of both macOS (to macOS Sequoia 15.0.1) and Firefox Developer Edition (to 132.0b3 (aarch64)), the Bookmarks Toolbar stopped working. The same issue appeared on my Windows PC.
Bookmarks toolbar is visible, I can show and hide it but it does not display any of my saved bookmarks. Luckily, they were not deleted and I still can access them via Bookmarks Menu, which is less than optimal.
The Drag&Drop functionality does not work either. When I grab the opened Tab, drag it on the Toolbar and release it, the Tab gets opened in the new browser window and it's not saved.

I am not sure what to do first. I already paid for the VPN subscription. I reinstalled Mozzilla VPN but have not yet put the sudo lines in that are listed in the help on Firefox. Can you send me an email with instructions and any special sudo lines I need to intall so I do not get charged a second time. I heve the recovery code. I am new to Mint. Windows 11 started knocking out my hardware with power surges. Had to come from the operating system itself since the machine is hooked to a power backup that smoothes the current out. Converted everything to Linux. Like it. Life can be cruel... LOL Thanks so much for the effort. [edited] landline, but best bet is email. [edited phone# and email from community support forum]
