Firefox Portable

Portable Firefox takes a long time to load a website – sometimes

Submitted by mgagnonlv on June 18, 2021 - 4:52pm

I regularly use Firefox Portable (currently v. 89) and I am confronted with this issue.

If I quit Firefox Portable normally and restart it, it loads in a decent amount of time (maybe 10 seconds before it loads a page). Same behaviour on the desktop version of Firefox, by the way. Likewise if I close my session but don't turn off my computer.

FF portable as default browser + multiple instances

Submitted by sortableapps on June 7, 2021 - 12:50pm

User has successfully used a third-party tool to register FF portable as the default browser in Windows.

User wants to be able to retain this setting while launching other instances (different versions) of FF portable.

When AllowMultipleInstances=true is set in .ini, the default browser setting no longer works correctly. For example, clicks to hyperlinks in the system or via other apps will now open the wrong FF instead of the default instance.

John, you could have warned us.........

About FF v89 that it was a major UI change, a major cock-up IMHO.
For the past few years, after the last UI change and it was working well up to v.88 I was using Aris' userChrome.css tweak to keep my tabs below
the address bar {no Bookmarks bar, turned off in the drop-down} from over at GitHub.
Now v89 has destroyed it and over at mozzillazine guys like me are scrambling to try to find ways of fixing it.
It seems that the silent majority, me included, like our tabs on the bottom and Mozilla themselves is not listening.

another instance of firefox is already running

Submitted by novw on May 10, 2021 - 7:08am

Another update. another F-up. Every time I try to open a (web-)link from an outside program (mail, excel, ...) I get a popup telling me "another instance of firefox is already running. Please close other instances of firefox before launching mozilla firefox, portable edition". If I completely ignore the popup (=leave it open), en click the SAME link a second time, it is opened in firefox portable. But that requester remains open till I click it . So: opening a weblink is now a "please click three times, because FF does not like users" thing? Any solution ideas?

FirefoxPortable on Windows 10?

Submitted by cbaxterm on April 30, 2021 - 10:30am

I am using FirefoxPortable v88. This works perfectly under Windows 7 but when the same flash drive is started using Windows 10 64-bit I receive the following message:

"You've launched an older version of Firefox
Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox.

Firefox portable has problems with some authority's certificate

Submitted by kanu on April 30, 2021 - 9:13am

For example
That's the Spanish Government's Ministry of Justice website. While trying to load the browser finds a certificate but it spits SEC_ERROR_UNKNOWN_ISSUER and the web won't go HTTPS.

I guess this won't be the only official website that has this problem.
