Firefox showing weird thai characters for specific letter combinations

Whenever I type `fi`, `ff` or `fl` in the address bar, firefox is displaying it as some (I presume) thai character.

This is when I type jeff.com

This is when I type flipkart.com

Check the address bar in this example:

Everything else - the page itself, the title bar, renders fine. I am not sure why it affects only the address bar. I pretty often run `pacman -Syu`, so I am not sure which update triggered this exactly - as I might've taken some time to notice this. I believe this has something to do with TTF ligatures and there is a different font that is used for the address bar which is somehow containing the wrong glyph, or something similar?

Please don't post oversized pictures.

As for the problem, which fonts do you have installed and what is your locale?

Edit: Oh and are you using some input method framework like ibus or scim? That would explain why it is only happening in the location bar - since it is user editable.

I got that after a font update (I think that was it). Although on some pages from a specific website, I also got screwy text in the page itself. MOST pages were fine though...

It went away after I restarted Firefox.

1. Apologies for that. I will surely keep it in mind.
2. My locale is set to en_US. I have around 270 fonts installed, the standard ones, plus a couple of fonts for devanagari. Would you like me to pastebin a list of fonts on my system?
3. No, I do not have ibus or scim or any other IME installed. Also I just noticed that this happens in the tab title as well http://i.imgur.com/nOz38lN.png

Re: Firefox showing weird thai characters for specific letter combinations

I had a similar issue some days ago, though I noticed it on usual websites, including this forum, i.e. not in the address bar.
It did not vanish after a first restart, though I must admit that restarting means killing and restarting to me; but it seems to be normal now.

Re: Firefox showing weird thai characters for specific letter combinations

Popping in to say that this is most likely due to the firefox update:

[2016-03-21 14:58] [ALPM] upgraded firefox (44.0.2-2 -> 45.0.1-1)

The only other remotely-related package I found in pacman.log was iso-codes:

[2016-03-21 14:59] [ALPM] upgraded iso-codes (3.65-1 -> 3.66-1)

Restarting firefox fixed the issue, in any case, so it may only apply when you've run the update while firefox was still open.
