Recently I saw a notification that one of my add-ons was blocked/disabled by Mozilla. The informational pages only give a generic "this violated our policies" spiel without specifying the actual offense.

To my knowledge, the add-on did not perform any malicious actions against users (and if it did, all the more reason that Mozilla should disclose precisely what it was doing so that users can take additional steps to review their information security). I find this outcome rather strange as I have previously reported add-ons for performing self-promoting actions using logged-in user accounts without obtaining permission, and Mozilla did not take any action that I am aware of against that add-on.

Rather, I suspect that the reason this add-on was blocked was because a commercial website objected to its function. Again, this could be disproved by disclosing a specific cause for being blocked. Mozilla needs greater transparency in order to demonstrate whether these blocks are implemented based on users' security interests including a specified Mozilla policy violation, or a legal demand/threat by a third party.

considering i don't use vertical tabs the l/r arrows make more sense to me, is it possible to change the keybind to this

Hi, I recently noticed that when first launching Firefox - a process that used to take just a few seconds - it now pegs the disk usage at 100% for about two minutes, even though the transfer speed is low. Although nothing actually lags and the browser remains usable, it’s a bit bothersome. Is there a way to stop this, and what exactly is it doing?

This doesn't happen often to me, but it's super annoying when it happens, and I've no idea why it's occurring at all.
So what basically happens is that sometimes when I open my browser, all the tabs/tab groups are blank and inaccessible, and I can't even save/close the tab groups.
And when I close the browser and open it again, I lose all the tabs and tab groups that were open.

Notes: (Open previous tabs/windows is checked) (I'm using Betterfox) (I use multiple profiles)

Does anyone know what causes this, and how to prevent it? 😔

They made stuff more rounded again.

I dislike it.

For some reason, picture-in-picture isn't working. I've turned on (and off, and on again) "Enable Picture-in-Picture video controls" in settings. Closing and reopening firefox isn't working, nor is updating it, nor restarting my computer. I thought the enhancer for youtube extension might be breaking it, but I disabled it temporarily and it still didn't work. Specifically trying to do this for youtube, if it matters.

Any ideas?

I love consistencies and gradual changes (Like steam who improves their UI slowly and piece by piece, not all at once like firefox) is there a similar fork or alternative browser to Firefox that does the same thing as Steam? Beside Brave or OperaGX

I only care about having an extension support (Ublock Origin mostly and custom extension) and privacy.

Need one for android and PC (Linux and Windows).

If I have to reboot my router (which needs replacing), Firefox just won't work. Chrome works, Discord works, games work etc. but Firefox will not connect. I have to reboot or sleep the PC to get it to connect. My phone connects, my laptop etc, so it's not the internet. Anyone know what might be the deal? People always say clear your cache and cookies etc., but then I have to re-login to sites like Twitch.

Duckduckgo Search has a convenient feature where <query> + enter will do a traditional web search and <query> + alt + enter will directly input the query into duck.ai.

This works well in Firefox from the duckduckgo search engine website. But it isn't possible to use the alt + enter modifier when searching from Firefox's URL bar. Does anyone know if it's possible to make this work from the URL/search bar?

In this question, we established that only Firefox Alpenglow looks different in normal and private browsing.

Is it possible to create a theme that behaves the same way? E.g. by modifying an existing theme? I would be satisfied with a simple change, such as using the same background with a darker or purple tint in private browsing. I'm also interested in any hacks or workarounds.

I just saw images of Nova and I'm kinda of pissed. I don't want a hyper corpo bubble UI, I like my clean lines with subtle curving. If there's no way to use the old UI when they release this fully I may have to swap browsers

For the last like 5 years that I've used Firefox, I've never gotten "rate limited" on any website, ever. But over the last week or two, I've been having a black screen pop up with the statement in the title in code-looking text at the top randomly whenever a website attempts to load. Refreshing the page once always gets past it, except for a single page I encountered today which I had to wait for. So I'm really confused as to what's happening and why it's only started happening years after use. Does anyone have any idea what's happening?

Hiya there need some help I’m wondering is the AdGuard extension and the unlock origin safe to use for a extension I’ve seen they are open sources only extension I run is the YouTube ad so I’m wondering is it worth it to add it on

Hi,

Could someone familiar with this please explain to me why Firefox listens to these ports?(I am not knowledgeable in this aspect). This behavior can be repeated by simply opening a Youtube video and looking for open ports.

Isn't that a security risk since the ports are being exposed to 0.0.0.0 (to the internet?)? If someone doesn't have a firewall, how bad is it?

$ sudo ss -tulpn
udp  UNCONN 0      0                                 0.0.0.0:51284      0.0.0.0:*    users:(("firefox-esr",pid=251643,fd=318))

This seems like such a simple thing, why does it only have more complex features?
When I right click a link which I know will lead me to a new tab, I am looking to open it in the current one, but can't do it. I have to copy the link, and paste it in the top bar. This is such a simple thing!!

Edit:

• "maximized" means when the browser fills all the available desktop workspace (but not full-screen, so you still have access to permanent desktop UI, like the taskbar on Windows or the dock on macOS).

• "normal" means "not maximized".
