Firefox lately seems to create problems every time it is updated. I am really leaning towards making MSEdge my default browser because I am tired of these problems cropping up at each major update. I spent several hours this morning making sure my bookmarks and my saved logins and passwords were up to date with what I have in Firefox plus making sure my privacy and security were at it's tightest and strongest there. Major updates for Firefox use to go smoothly and seamlessly but that is now questionable.

The Firefox Color extension (which says "Official extension built by Mozilla.") has made it so that when I right click a link and select bookmark link, the menu for choosing which folder to place the bookmark is forced to be dark mode. Due to how few sites I use dark mode on, this sudden reversal of colors makes it hard to read. I tried changing every setting to blue but none of them seemed to effect it. I couldn't find anywhere on the extension page to ask about this without leaving a review so I found my way here. How do I fix this, and if I can't, when is it going to be fixed?

bold text

Using a Mac Monterey 12.7.6 and uptodate firefox.

Trying to use "tree style tabs". I'm trying to drag and drop a tab named "CHILD" to a tab named "PARENT". Instead of appearing in the tab PARENT the CHILD tab disappears and its content is added to the PARENT tab.

I would prefer the child tab to nest within the parent tab.

Thank you!

How do I escalate the presence of a malicious extension for removal from the store?

[Coupongogo: Automatic Coupons & Cashback](https://addons.mozilla.org/en-US/firefox/addon/coupongogo-automatic-coupons/) is a malicious extension programed with a command and control server located in China.

Despite [Firefox user reports](https://www.reddit.com/r/firefox/comments/1pl0u6m/malicious_addon_does_not_get_taken_down/), the extension remains available on the Mozilla addon store.

A [rastersec.com contributor explains](https://www.rastersec.com/blog/coupongogo-cryptostealer),

>\[Coupongogo\] operates as a remote-controlled time bomb, utilizing a dynamic configuration system to evade detection, hijack all search and browsing traffic, and wait for a server command to activate its dormant theft capabilities targeting major cryptocurrency exchanges.

Given the lack of success at securing the privacy and security of users by using the standard addon reporting tool, how can I escalate this matter to a responsible Mozilla party for triage?

Well, well, well. Latest Firefox update and what did you folks send along to take over my PC screen when I log-in? This: https://getadblock.com/en/update/latest/?f=f&version=6.31.1&u=68uu84zt49066849&bc=3072&rt=0

Clever, clever, clever aren't you folks?

1. I have NEVER downloaded "adblock" 2. "Adblock" cannot be found in the PROGRAMS listed on my PC, so no way to "uninstall" your uninvited, unwelcome, unneeded bit of buy-this-buy-this-buy-this angling. 3. "Adblock" cannot be found on a search of the registry. 3. What a pathetic approach, Firefoxers!

Firefox Root Certificate Expiration related issue w/ legacy add-ons & single website access

I'm on WinXP and Win7; FF is there respectively on ESR 52.6.0, and 56.0.2.

    • Pls refrain from lecturing me on updating etc. I need it to be this way for umpteen reasons. Thanks for understanding.**

First, all of a sudden all my legacy add-ons were disabled. Most of them ensure FF looks like it did ages ago, which is what I'm used to, and need, to function properly myself. They overall are no longer maintained or downloadable, hence the need to stay on lower browser versions as well.

Managed to fix that.

Then, last Fri, my webmail provider missed updating their security certificate. They seemingly later do, but I am left unable to access their website from FF on both machines, and Chrome on the XP. Disaster.

The error messages I get are, in FF:

[www.netaddress.com] uses an invalid security certificate.

The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported.

Error code: <a id="errorCode" title="SEC\\\\\\\\\\\\\\\_ERROR\\\\\\\\\\\\\\\_UNKNOWN\\\\\\\\\\\\\\\_ISSUER">SEC\_ERROR\_UNKNOWN\_ISSUER</a>

and in Chrome:

classic.netaddress.com normally uses encryption to protect your information. When Google Chrome tried to connect to classic.netaddress.com this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be classic.netaddress.com, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Google Chrome stopped the connection before any data was exchanged.

You cannot visit [classic.netaddress.com] right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later.

When running a SSL server test on their certificate it turned back: Chain issues Incorrect order, Contains anchor

No idea if that's relevant.

I tried just abt everything I was handed, could think of, or googled. Adding an exception included. Nothing works. Logically, the error should be on their end (w/ their old certificate, it all worked fine, now it doesn't), but somehow I keep being directed to that your root certificate having expired is the culprit.

Earlier today, I took the plunge and updated FF to 72.0.2 on the Win7 machine. (My webmail doesn't have full functionality on Chrome, so I was still very hampered in that regard there.) Now I can access the webmail -- but all my add-ons AGAIN are disabled. And what I did before to make the work does now NOT work anymore.

Can someone pls take me out of my misery? My whole existence is falling apart. I am already on 75 % (invisible) disability. Nothing works, least of all I. I am days behind on an already massively overburdened schedule. Not everyone can handle constant updates and their user interface being changed all the time. Some ppl are dependent on things looking and acting the exact same.

I'd like my add-ons back functional on the Win7 machine, and my webmail back -- INCLUDING the add-ons remaining functional, on the WinXP. Thank you.
