It works but I think it doesn't nescessary to open a new window, just an inline popup would work better and I could just press Esc to close.
Checks out, what I can't see in CSS.
Awesome! Very Useful! Love It! <3
I'm a developer and I use the extension to test stylesheets and to inspect exceptional typography I encounter. It has become an essential tool in my daily workflow.
Ultra pratique, complet, indispensable…
After the latest firefox update, it stopped working :(
Amazing works well for me! Good job!
Helpful and useful tool.
Excellent, worked for me. Thanks :-)
I love this extension. However, lately I can't get it to work right on Firefox Developer Edition. It works fine on Firefox Stable. On Dev, when I click text, the window pops up but is completely blank with no information where normally all the text CSS properties would be.
Apesar de não ter o tamanho da fonte em PT, mas em PX... Vale a pena. Exibe com precisão em pop-up as informações como "Elemento", "tamanho" em pixels e um link para avaliar a fonte no site "Fonts". O menu de contexto funciona no Firefox 58 para Windows 10 com a opção Inspect Font ou Analyse Selection conforme a seleção do texto. A extensão é uma ferramenta útil por sua precisão e rapidez.
Would be five stars but it needs to have the Font Size in pt, not px as most designers work in pt. Also would be good to incorporate the em size as well as some designers use this as well.
Very handy for its purpose!
Such a handy tool for designers who are always looking for new and old fonts to use. Great add on! Works great.
It's nice to see the info condensed in one window, but that's about it. Where (from which cssfile or override or ...) the font got its settings that is what I was hoping to see.
Instead of the "4 key pieces of functionality" listed for the old XUL version of this add-on, this WebExtension version's description lists "3 key pieces". Unfortunately, as far as I can tell, only the first two have actually been implemented. Supposedly, "Any active element can have any piece of the font's options (such as color, size or family) adjusted inline", but with the WebExtension version, the context menu only has a single option, "Inspect Font", and none of the fields in its popup are modifiable. I also checked the screenshots and the FAQ (which, BTW, uses the misspelling "Fond Finder" in multiple places), to no avail.
If you need the actual font substitution functionality, it appears that for now you'll need to stick with the XUL version of Font Finder (which of course will stop working next month unless you migrate to Firefox ESR or a fork like Pale Moon). Just watch out for the infinite popup loop the XUL version gives you the first time you restart after installing it in a profile — see my review of that add-on for more details.
My final note is that neither the XUL version nor the WebExtension version actually address the problem I installed them for. Their descriptions say "Information Captured: [...] Font family (including actual font being rendered!)", which I was expecting to help me debug the problem I was having on Linux with extremely messed-up scaled-bitmap, all-caps font substitutions (even when the exact TrueType font specified in the stylesheet was installed). Unfortunately they don't tell you the "actual font being rendered" — they just tell you the font that the web page *requests* to be rendered. I then learned about running Firefox with the environment variable FC_DEBUG=1, but its output didn't give me any useful information about the incorrect substitution. Luckily after a bunch more Googling, I was able to figure out that going to about:config and setting gfx.font_rendering.fontconfig.fontlist.enabled = false would cause Linux Firefox to go back to the old Cairo-based font rendering rather than the broken Firefox 44+ version.
I love it
Very useful for any designer like me.
