If I saw this extension earlier in my career, I would've shunned this away in a heartbeat. However, since I worked for a bioinformatics startup company, bioFOX was definitely intriguing to me.
After installing the extension (which was easy), I activated the sidebar and started looking at how to use the extension. Granted, the extension is a little intimidating, but I was determined to see what it was all about.
The whole premise of the bioFOX extension is to take highlight Genomic Sequences in the browser or the workarea provided to us through the bioFOX extension and then click on where you wanted to send them.
For example, if you wanted to see the reverse of a particular sequence, you would do one of two things: Click on workspace at the top of the bioFOX sidebar, type in your data, and click submit. Highlight the sequence in the browser window and click on the Reverse item under Nucleotide and it'll reverse your sequence that you highlighted; and the second way is just to highlight a sequence in the browser and click where you want to send the sequence to.
These are very simple tools for a biochemist, but a bioinformatics company could take their own processes and adopt them into their own custom extension. This would allow specialized Firefox extensions for employees or better yet, potential customers or clients.
Since this extension is very specific and geared towards bioinformatics, most people will veer away from this type of extension, but from what I've seen, I think it has potential for people to experiment with it just to get a feel for bioinformatics.
