Firefox – Get Your Arrow Keys to Scroll Properly

Friday, November 17th, 2006

My friend, if a little cursor jumps all around the words on your screen when you use the arrow keys in Firefox, then you may have caret browsing mode turned on. Don’t panic.

Just hit your F7 key while in Firefox. It’s that simple! What it does is toggles caret browsing mode. When that mode is turned on, using the arrow keys and the pageup/pagedown keys will move the little caret/cursor around the text in the browser window instead of scrolling the page like you probably want.

Yeah, so somehow this mode got toggled for you. In Ubuntu it may be the default, at least for me.

Here’s where I found this answer.

Fixing Firefox Cannot Use the Profile …Error Messages

Monday, July 24th, 2006

Answer:
This MozillaZine Profile-in-use article will tell you everything you need to know to solve this.

Note: In my case using Ubuntu Dapper I located these “locked” files in this directory:
/home/chiefinnovator/.mozilla/firefox/q5ocj63r.default
More generally that pattern is:
~/.mozilla/firefox/[some random looking letters.default]

And the quickest way to delete this files is to open up a terminal and run these two commands (altered for your respective locations):
$ sudo rm /home/chiefinnovator/.mozilla/firefox/q5ocj63r.default/lock
$ sudo rm /home/chiefinnovator/.mozilla/firefox/q5ocj63r.default/.parentlock

Making FireFox Browse a Local Directory

Tuesday, May 9th, 2006

By default Firefox does not allow you to follow hyperlinks to local directories.

To change this for versions of Firefox <1.5, this Mozilla Knowledge base article tells us to:

Type about:config into the Location bar and hit Enter. Find the entry for security.checkloaduri and change its value to false by double-clicking it. Then, restart your browser.

For newer versions of Firefox just follow the complex sounding instructions from that article. Alternatively this Firefox extension: Policy Manager may give you an easier go at it.

Firefox 1.5 – Illegal Operation in Plug-in (Shockwave Flash)

Lately it seems like every say 1 in 10 pages I visit Firefox pops up this error:

Illegal Operation in Plug-in
————————-
The Plug-in performed an illegal operation. You are strongly advised to restart Firefox.
[ ] Don’t show this message again during this session.
—-
OK

Here’s a picture.
Illegal Operation in Plug-in

This forum post sounds like the answer so go knock yourself out. (It sounded like too much work for me this morning so I’m going to just keep clicking the OK button :-( )

Update:
I tryed the instructions from the link above and didn’t have any luck, but here are a few other advice pages to try:

Problem with Plugin “Shockwave Flash”

Update Update:
Give Hugo’s advice in the comment below a try. It certainly sounds promising.

Update Update Update:
Lukpuk comments below that it may be a virus. He reccomends to run msinfo32.exe and find something weird in loaded modules or autorun. Then try to delete a virus in windows/system32/ (He used Hijack this) during the boot.
